CVE-2025-53102 Discourse's WebAuthn challenge isn't cleared from user session after authentication

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...
