Pyodide is an open-source project run by the volunteers and contributors, so we do not have a dedicated security response team or a bug bounty program.
Only the main branch of all the Pyodide runtime and other related components is actively maintained. If you are using an older version, please upgrade to the latest release to receive fixes.
When reporting a security issue, ensure that it can be reproduced on the latest main branch.
