CVE-2025-53102 – Discourse Unauthenticated WebAuthn Challenge Leak

CVE ID : CVE-2025-53102

Published : July 29, 2025, 8:15 p.m. | 1 hour, 12 minutes ago

Description : 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.

Severity: 0.0 | NA
