PyJWT 2.13.0 — Security Release

This release bundles five security fixes plus three additional hardening / spec-compliance changes. We recommend all users upgrade.

Security

• GHSA-xgmm-8j9v-c9wx — JWK JSON accepted as HMAC secret (algorithm confusion). HMACAlgorithm.prepare_key previously rejected PEM- and SSH-formatted asymmetric keys but did not catch a JWK passed as a raw JSON string. In a verifier configured with both symmetric and asymmetric algorithms in algorithms=[…] and a raw-JSON JWK as the key, an attacker could forge HS256 tokens using the JWK text as the HMAC secret. The guard has been extended to reject any JWK-shaped JSON. Reported by @​aradona91.

• GHSA-jq35-7prp-9v3f — Algorithm allow-list bypass with PyJWK / PyJWKClient. When verifying with a PyJWK, the caller's algorithms=[…] allow-list was checked against the token header alg as a string only; actual verification used the algorithm bound to the PyJWK. An attacker who controlled a registered JWKS key could sign with one algorithm and advertise another on the header. PyJWT now requires the token header alg to match the PyJWK's algorithm before verification. Reported by @​sushi-gif.

• GHSA-w7vc-732c-9m39 — DoS via base64 decode of unused payload segment when b64=false. For detached-payload JWS (b64=false), the compact-form payload segment was base64-decoded before being discarded in favor of the caller-supplied detached_payload. An attacker could inflate the unused segment to force CPU + memory cost without holding a valid signature. The segment is now required to be empty per RFC 7515 Appendix F, and is no longer decoded. Reported by @​thesmartshadow.

• GHSA-993g-76c3-p5m4 — PyJWKClient accepts non-HTTP(S) URIs. PyJWKClient.fetch_data passed its URI to urllib.request.urlopen, which by default also handles file://, ftp://, and data: schemes. An application that fed an attacker-influenced URI into PyJWKClient could be coerced into reading local files or reaching other unintended schemes. PyJWKClient now rejects any URI whose scheme isn't http or https. Reported by @​KEIJOT.

• GHSA-fhv5-28vv-h8m8 — PyJWKClient cache wiped on fetch error. A finally-block put(jwk_set=None) cleared the JWK Set cache whenever a fetch raised, turning a transient JWKS-endpoint outage into application-wide auth failure. The cache write was moved into the success path; transient errors no longer evict valid cached keys. Reported by @​eddieran.

Fixed

• Reject empty HMAC keys outright in HMACAlgorithm.prepare_key with InvalidKeyError instead of accepting them with only a warning. Defends against the os.getenv("JWT_SECRET", "") footgun. Thanks to @​SnailSploit and @​spartan8806 for the reports.
• Forward per-call options (including enforce_minimum_key_length) from PyJWT.decode through to PyJWS._verify_signature. The option was previously silently dropped between the two layers, so it only took effect when set on the PyJWT instance. Thanks to @​WLUB for the report.
• RFC 7797 §3 compliance for b64=false: the encoder now auto-adds "b64" to crit, and the decoder rejects tokens that set b64=false without listing it in crit. Thanks to @​MachineLearning-Nerd for the report.

Changed

• Migrate the dev, docs, and tests package extras to dependency groups, by @​kurtmckee in #1152.

Upgrade notes

Most fixes are invisible to correctly-configured callers. A few behavioral changes you may encounter:

• Empty HMAC keys now raise. If your app passed "" or b"" as a secret (often via a missing env var, e.g. os.getenv("JWT_SECRET", "")), encode/decode will now raise InvalidKeyError. This is the intended behavior — fix the configuration.
• PyJWK decoding now requires the token's alg to match the JWK's algorithm. Previously a mismatch was silently honored if the header alg appeared in the allow-list. Tokens that relied on this mismatch will now fail with InvalidAlgorithmError.
• PyJWKClient now rejects non-HTTP(S) URIs at construction time. Tests or dev environments that fetched JWKS from file:// URIs need to switch to a local HTTP server or load the JWKS by other means (e.g. construct PyJWKSet.from_dict(...) directly).
• b64=false tokens are now strictly RFC 7515 / 7797 compliant. Tokens with a non-empty compact-form payload segment, or that omit "b64" from crit, will be rejected. PyJWT-produced tokens always satisfy both invariants, so round-trips through PyJWT are unaffected.
• enforce_minimum_key_length set per-call now takes effect. Callers who passed options={"enforce_minimum_key_length": True} to jwt.decode() previously got no enforcement; they will now get InvalidKeyError on undersized keys, as documented.

Sourced from pyjwt's changelog.

v2.15.0 <https://github.com/jpadilla/pyjwt/compare/2.14.0...2.15.0>__

Security

- Wrap recursion errors from deeply nested JWT payloads in ``DecodeError``
  instead of exposing a raw ``RecursionError``.
Added

- Support Python 3.15 by @kytta in `[#1202](https://github.com/jpadilla/pyjwt/issues/1202) <https://github.com/jpadilla/pyjwt/pull/1202>`__
Changed



JWKSetCache now stores the parsed PyJWKSet rather than the raw JWKS
payload, so a cache hit no longer re-parses every key. JWKSetCache.put()
accepts either form and raises PyJWKSetError for anything else. As a
result, PyJWKClient.get_jwk_set() returns the same PyJWKSet instance
for as long as it stays cached, rather than a freshly built one per call in
[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>__
PyJWKClient.fetch_data() now raises
PyJWKClientError("The JWKS endpoint did not return a JSON object") when
the endpoint response is not a JSON object, instead of returning it for
get_jwk_set() to reject. Callers reaching the JWKS through
get_jwk_set() see the same error as before in
[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>__

Fixed

- Return cached ``PyJWKSet`` values from ``PyJWKClient.get_jwk_set()`` instead
  of raising ``PyJWKClientError("The JWKS endpoint did not return a JSON
  object")``. ``JWKSetCache.put()`` documents ``PyJWKSet`` as the cached value,
  so callers pre-populating the cache to avoid a network round-trip could not
  read it back in `[#914](https://github.com/jpadilla/pyjwt/issues/914) <https://github.com/jpadilla/pyjwt/issues/914>`__ and
  `[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>`__
- ``PyJWKClient.get_jwk_set()`` now caches the key set it returns, so a
  ``fetch_data()`` override that filters or transforms the JWKS is no longer
  undone by the next cache hit in
  `[#1208](https://github.com/jpadilla/pyjwt/issues/1208) <https://github.com/jpadilla/pyjwt/pull/1208>`__
- Raise the documented ``PyJWTError`` subclass instead of leaking a
  ``TypeError`` when the ``exp``, ``nbf``, or ``iat`` claim decodes to a
  non-numeric, non-string value such as a list, dict, or ``null``.
- Reject OKP JWK private keys when their public ``x`` component does not
  match the private ``d`` component.
- Treat malformed JWK Set members as unusable keys rather than letting
  ``AttributeError`` or ``TypeError`` escape ``PyJWKSet``. A member that is not

Updates urllib3 from 2.2.3 to 2.8.0

Release notes
Sourced from urllib3's releases.

2.8.0
🚀 urllib3 is fundraising for HTTP/2 support
urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.
Thank you for your support.
Security
Fixed the following security issues:

The TLS configuration for HTTPS proxies could be ignored or overridden. (High severity, GHSA-8988-9cw3-xx77)
HTTPResponse.stream() and read_chunked() could buffer a chunk-size line of unbounded length in memory. (High severity, GHSA-vxq7-64xx-v4gw)
Chunked Deflate streaming could enter an infinite loop. (Medium severity, GHSA-gh4c-6fx4-qh6g)


[!IMPORTANT]
urllib3 2.8.0 fixes HTTPS proxy TLS configuration being ignored or overridden by destination settings. Configurations relying on that behavior may require changes.
Configure proxy CA certificates and client certificates in proxy_ssl_context, and proxy identity checks with proxy_assert_hostname or proxy_assert_fingerprint. Destination client certificates and identity overrides no longer apply to HTTPS forwarding proxy connections.


[!NOTE]
CVE IDs had not yet been assigned to these advisories at the time of release due to a backlog at GitHub's CNA.

Deprecations & Removals

Deprecated using an empty collection as the Retry option allowed_methods to retry any verb. (#5044)

Features

Added Url.auth_decoded and Url.auth_decoded_joined convenience properties to the result of parse_url(). (#4945)
Added basic_auth_encoding and proxy_basic_auth_encoding parameters to urllib3.util.make_headers(). (#5092)

Bugfixes


Fixed response header handling to replace obsolete folded header lines (obs-fold) with spaces in accordance with RFC 9112, preventing raw CRLF sequences from appearing in header values such as Set-Cookie. (#1362)


Fixed usage of proxy_ssl_context with ProxyManager when use_forwarding_for_https=True. Passing ssl_context instead of proxy_ssl_context for HTTPS proxies in this configuration now emits a FutureWarning and will raise an error in v3.0. (#2577)


Changed behavior of the default ConnectionPool.pool initialization. LifoQueue is now resolved from the queue module after the ConnectionPool is instantiated instead of using the default cached QueueCls class property. This is done because sometimes the queue.LifoQueue is monkey-patched late in the program, such as by gevent. (#3289)


Raised UnrewindableBodyError instead of ValueError when retrying a request whose body had tell() but not seek(). (#3779)


Decoded percent-encoded SOCKS proxy credentials before authenticating with the proxy server. (#3785)


Fixed HTTPResponse.drain_conn() to discard unread response data in 64 KiB chunks (same as the default amt when doing HTTPResponse.stream(...)). (#5019)


Fixed is_ipaddress() to detect non-standard IPv4 forms accepted by socket.connect, such as hex (0x7f000001), octal (0177.0.0.1), and decimal integers (2130706433), ensuring SSL certificate verification uses the correct mode for these addresses. (#5029)


Fixed HTTPConnectionPool.urlopen raising a misleading FullPoolError instead of ValueError when called with an invalid timeout argument on a pool created with block=True. (#5059)


Fixed port-zero handling to preserve explicit :0 values instead of substituting the default ports 80 or 443 in URL parsing, pool selection, proxy configuration, connection_from_url(), and HTTP/2 request authority. (#5071, #5101)


Fixed a bug where PoolManager passed the assert_hostname and assert_fingerprint parameters to HTTP connection pools. (#5077)


Fixed HTTPConnectionPool.urlopen() and HTTP proxy forwarding to strip URL fragments from absolute request targets before sending requests. (#5079)


Added safeguards to the proxy tunneling code to prevent potential security issues when handling invalid characters in the proxy host and HTTP headers. This change affects users of Python 3.10, Python 3.11, and Python 3.12 when the standard library does not contain the fix; those on newer Python versions should upgrade to 3.13.14+ or 3.14.5+ to get the same security fixes. (#5091)


Fixed HTTPSConnection.connect() overriding ProxyConfig.ssl_context's certificate policy and proxy identity checks with the target connection's TLS settings when forwarding through an HTTPS proxy.
HTTPSConnection no longer applies target SNI, assertions, or client credentials to forwarding proxy handshakes and continues to use its ssl_context as a fallback when an HTTPS proxy forwards an HTTP target. (#5093)


Fixed URL parsing to more strictly enforce RFC 3986 host syntax, rejecting invalid host input such as raw spaces and control characters, malformed percent-encodings, and percent-encoded control characters in HTTP(S) hosts and IPv6 zone identifiers, including proxy CONNECT tunnel targets. Host normalization now also follows RFC 3986 normalization rules for percent-encoded octets by decoding percent-encoded unreserved characters and uppercasing the hexadecimal digits of retained percent-encoded octets. (#5095)

Updates pyjwt from 2.12.1 to 2.15.0

Release notes
Sourced from pyjwt's releases.

2.15.0
See the 2.15.0 changelog for complete release details.
2.14.0
See the 2.14.0 changelog for the complete release details and related security advisories.
2.13.0
PyJWT 2.13.0 — Security Release
This release bundles five security fixes plus three additional hardening / spec-compliance changes. We recommend all users upgrade.
Security


GHSA-xgmm-8j9v-c9wx — JWK JSON accepted as HMAC secret (algorithm confusion). HMACAlgorithm.prepare_key previously rejected PEM- and SSH-formatted asymmetric keys but did not catch a JWK passed as a raw JSON string. In a verifier configured with both symmetric and asymmetric algorithms in algorithms=[…] and a raw-JSON JWK as the key, an attacker could forge HS256 tokens using the JWK text as the HMAC secret. The guard has been extended to reject any JWK-shaped JSON. Reported by @​aradona91.


GHSA-jq35-7prp-9v3f — Algorithm allow-list bypass with PyJWK / PyJWKClient. When verifying with a PyJWK, the caller's algorithms=[…] allow-list was checked against the token header alg as a string only; actual verification used the algorithm bound to the PyJWK. An attacker who controlled a registered JWKS key could sign with one algorithm and advertise another on the header. PyJWT now requires the token header alg to match the PyJWK's algorithm before verification. Reported by @​sushi-gif.


GHSA-w7vc-732c-9m39 — DoS via base64 decode of unused payload segment when b64=false. For detached-payload JWS (b64=false), the compact-form payload segment was base64-decoded before being discarded in favor of the caller-supplied detached_payload. An attacker could inflate the unused segment to force CPU + memory cost without holding a valid signature. The segment is now required to be empty per RFC 7515 Appendix F, and is no longer decoded. Reported by @​thesmartshadow.


GHSA-993g-76c3-p5m4 — PyJWKClient accepts non-HTTP(S) URIs. PyJWKClient.fetch_data passed its URI to urllib.request.urlopen, which by default also handles file://, ftp://, and data: schemes. An application that fed an attacker-influenced URI into PyJWKClient could be coerced into reading local files or reaching other unintended schemes. PyJWKClient now rejects any URI whose scheme isn't http or https. Reported by @​KEIJOT.


GHSA-fhv5-28vv-h8m8 — PyJWKClient cache wiped on fetch error. A finally-block put(jwk_set=None) cleared the JWK Set cache whenever a fetch raised, turning a transient JWKS-endpoint outage into application-wide auth failure. The cache write was moved into the success path; transient errors no longer evict valid cached keys. Reported by @​eddieran.

Reject empty HMAC keys outright in HMACAlgorithm.prepare_key with InvalidKeyError instead of accepting them with only a warning. Defends against the os.getenv("JWT_SECRET", "") footgun. Thanks to @​SnailSploit and @​spartan8806 for the reports.
Forward per-call options (including enforce_minimum_key_length) from PyJWT.decode through to PyJWS._verify_signature. The option was previously silently dropped between the two layers, so it only took effect when set on the PyJWT instance. Thanks to @​WLUB for the report.
RFC 7797 §3 compliance for b64=false: the encoder now auto-adds "b64" to crit, and the decoder rejects tokens that set b64=false without listing it in crit. Thanks to @​MachineLearning-Nerd for the report.

Changed

Migrate the dev, docs, and tests package extras to dependency groups, by @​kurtmckee in #1152.

Upgrade notes
Most fixes are invisible to correctly-configured callers. A few behavioral changes you may encounter:

Empty HMAC keys now raise. If your app passed "" or b"" as a secret (often via a missing env var, e.g. os.getenv("JWT_SECRET", "")), encode/decode will now raise InvalidKeyError. This is the intended behavior — fix the configuration.
PyJWK decoding now requires the token's alg to match the JWK's algorithm. Previously a mismatch was silently honored if the header alg appeared in the allow-list. Tokens that relied on this mismatch will now fail with InvalidAlgorithmError.
PyJWKClient now rejects non-HTTP(S) URIs at construction time. Tests or dev environments that fetched JWKS from file:// URIs need to switch to a local HTTP server or load the JWKS by other means (e.g. construct PyJWKSet.from_dict(...) directly).
b64=false tokens are now strictly RFC 7515 / 7797 compliant. Tokens with a non-empty compact-form payload segment, or that omit "b64" from crit, will be rejected. PyJWT-produced tokens always satisfy both invariants, so round-trips through PyJWT are unaffected.
enforce_minimum_key_length set per-call now takes effect. Callers who passed options={"enforce_minimum_key_length": True} to jwt.decode() previously got no enforcement; they will now get InvalidKeyError on undersized keys, as documented.

v2.15.0 <https://github.com/jpadilla/pyjwt/compare/2.14.0...2.15.0>__
Security

- Wrap recursion errors from deeply nested JWT payloads in ``DecodeError``
  instead of exposing a raw ``RecursionError``.
Added

- Support Python 3.15 by @kytta in `[#1202](https://github.com/jpadilla/pyjwt/issues/1202) &lt;https://github.com/jpadilla/pyjwt/pull/1202&gt;`__
Changed



JWKSetCache now stores the parsed PyJWKSet rather than the raw JWKS
payload, so a cache hit no longer re-parses every key. JWKSetCache.put()
accepts either form and raises PyJWKSetError for anything else. As a
result, PyJWKClient.get_jwk_set() returns the same PyJWKSet instance
for as long as it stays cached, rather than a freshly built one per call in
[#1208](https://github.com/jpadilla/pyjwt/issues/1208) &lt;https://github.com/jpadilla/pyjwt/pull/1208&gt;__
PyJWKClient.fetch_data() now raises
PyJWKClientError(&quot;The JWKS endpoint did not return a JSON object&quot;) when
the endpoint response is not a JSON object, instead of returning it for
get_jwk_set() to reject. Callers reaching the JWKS through
get_jwk_set() see the same error as before in
[#1208](https://github.com/jpadilla/pyjwt/issues/1208) &lt;https://github.com/jpadilla/pyjwt/pull/1208&gt;__

Fixed

- Return cached ``PyJWKSet`` values from ``PyJWKClient.get_jwk_set()`` instead
  of raising ``PyJWKClientError(&quot;The JWKS endpoint did not return a JSON
  object&quot;)``. ``JWKSetCache.put()`` documents ``PyJWKSet`` as the cached value,
  so callers pre-populating the cache to avoid a network round-trip could not
  read it back in `[#914](https://github.com/jpadilla/pyjwt/issues/914) &lt;https://github.com/jpadilla/pyjwt/issues/914&gt;`__ and
  `[#1208](https://github.com/jpadilla/pyjwt/issues/1208) &lt;https://github.com/jpadilla/pyjwt/pull/1208&gt;`__
- ``PyJWKClient.get_jwk_set()`` now caches the key set it returns, so a
  ``fetch_data()`` override that filters or transforms the JWKS is no longer
  undone by the next cache hit in
  `[#1208](https://github.com/jpadilla/pyjwt/issues/1208) &lt;https://github.com/jpadilla/pyjwt/pull/1208&gt;`__
- Raise the documented ``PyJWTError`` subclass instead of leaking a
  ``TypeError`` when the ``exp``, ``nbf``, or ``iat`` claim decodes to a
  non-numeric, non-string value such as a list, dict, or ``null``.
- Reject OKP JWK private keys when their public ``x`` component does not
  match the private ``d`` component.
- Treat malformed JWK Set members as unusable keys rather than letting
  ``AttributeError`` or ``TypeError`` escape ``PyJWKSet``. A member that is not
&lt;/tr&gt;&lt;/table&gt;

Updates urllib3 from 2.6.3 to 2.8.0

Release notes
Sourced from urllib3's releases.

2.8.0
🚀 urllib3 is fundraising for HTTP/2 support
urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.
Thank you for your support.
Security
Fixed the following security issues:

The TLS configuration for HTTPS proxies could be ignored or overridden. (High severity, GHSA-8988-9cw3-xx77)
HTTPResponse.stream() and read_chunked() could buffer a chunk-size line of unbounded length in memory. (High severity, GHSA-vxq7-64xx-v4gw)
Chunked Deflate streaming could enter an infinite loop. (Medium severity, GHSA-gh4c-6fx4-qh6g)


[!IMPORTANT]
urllib3 2.8.0 fixes HTTPS proxy TLS configuration being ignored or overridden by destination settings. Configurations relying on that behavior may require changes.
Configure proxy CA certificates and client certificates in proxy_ssl_context, and proxy identity checks with proxy_assert_hostname or proxy_assert_fingerprint. Destination client certificates and identity overrides no longer apply to HTTPS forwarding proxy connections.


[!NOTE]
CVE IDs had not yet been assigned to these advisories at the time of release due to a backlog at GitHub's CNA.

Deprecations & Removals

Deprecated using an empty collection as the Retry option allowed_methods to retry any verb. (#5044)

Features

Added Url.auth_decoded and Url.auth_decoded_joined convenience properties to the result of parse_url(). (#4945)
Added basic_auth_encoding and proxy_basic_auth_encoding parameters to urllib3.util.make_headers(). (#5092)

Bugfixes


Fixed response header handling to replace obsolete folded header lines (obs-fold) with spaces in accordance with RFC 9112, preventing raw CRLF sequences from appearing in header values such as Set-Cookie. (#1362)


Fixed usage of proxy_ssl_context with ProxyManager when use_forwarding_for_https=True. Passing ssl_context instead of proxy_ssl_context for HTTPS proxies in this configuration now emits a FutureWarning and will raise an error in v3.0. (#2577)


Changed behavior of the default ConnectionPool.pool initialization. LifoQueue is now resolved from the queue module after the ConnectionPool is instantiated instead of using the default cached QueueCls class property. This is done because sometimes the queue.LifoQueue is monkey-patched late in the program, such as by gevent. (#3289)


Raised UnrewindableBodyError instead of ValueError when retrying a request whose body had tell() but not seek(). (#3779)


Decoded percent-encoded SOCKS proxy credentials before authenticating with the proxy server. (#3785)


Fixed HTTPResponse.drain_conn() to discard unread response data in 64 KiB chunks (same as the default amt when doing HTTPResponse.stream(...)). (#5019)


Fixed is_ipaddress() to detect non-standard IPv4 forms accepted by socket.connect, such as hex (0x7f000001), octal (0177.0.0.1), and decimal integers (2130706433), ensuring SSL certificate verification uses the correct mode for these addresses. (#5029)


Fixed HTTPConnectionPool.urlopen raising a misleading FullPoolError instead of ValueError when called with an invalid timeout argument on a pool created with block=True. (#5059)


Fixed port-zero handling to preserve explicit :0 values instead of substituting the default ports 80 or 443 in URL parsing, pool selection, proxy configuration, connection_from_url(), and HTTP/2 request authority. (#5071, #5101)


Fixed a bug where PoolManager passed the assert_hostname and assert_fingerprint parameters to HTTP connection pools. (#5077)


Fixed HTTPConnectionPool.urlopen() and HTTP proxy forwarding to strip URL fragments from absolute request targets before sending requests. (#5079)


Added safeguards to the proxy tunneling code to prevent potential security issues when handling invalid characters in the proxy host and HTTP headers. This change affects users of Python 3.10, Python 3.11, and Python 3.12 when the standard library does not contain the fix; those on newer Python versions should upgrade to 3.13.14+ or 3.14.5+ to get the same security fixes. (#5091)


Fixed HTTPSConnection.connect() overriding ProxyConfig.ssl_context's certificate policy and proxy identity checks with the target connection's TLS settings when forwarding through an HTTPS proxy.
HTTPSConnection no longer applies target SNI, assertions, or client credentials to forwarding proxy handshakes and continues to use its ssl_context as a fallback when an HTTPS proxy forwards an HTTP target. (#5093)


Fixed URL parsing to more strictly enforce RFC 3986 host syntax, rejecting invalid host input such as raw spaces and control characters, malformed percent-encodings, and percent-encoded control characters in HTTP(S) hosts and IPv6 zone identifiers, including proxy CONNECT tunnel targets. Host normalization now also follows RFC 3986 normalization rules for percent-encoded octets by decoding percent-encoded unreserved characters and uppercasing the hexadecimal digits of retained percent-encoded octets. (#5095)
