CVE-2025-53102
Discourse is an open-source community discussion platform. Prior to version 3.4.7 on the stable branch and version 3.5.0.beta.8 on the tests-passed branch, upon issuing a physical security key for 2FA, the server generates a WebAuthn challenge, which the client signs. The challenge is not cleared from the user’s session after authentication, potentially allowing reuse and increasing security risk. This is fixed in versions 3.4.7 and 3.5.0.beta.8.
