GHSA-f66q-9rf6-8795: Flask-Security-Too: WebAuthn reauthentication freshness bypass via cross-user assertion 0 Flask-Security-Too versions 5.8.0 and 5.8.1 contain a vulnerability in the WebAuthn reauthentication process that allows an authenticated attacker to bypass session freshness checks. The flaw occurs because the system marks a session as reauthentication-fresh after processing a WebAuthn assertion from any credential, without verifying that the credential belongs to the current session user. This enables an attacker who owns any WebAuthn credential registered on the deployment to satisfy the freshness gate of another user's session, potentially allowing sensitive actions that require recent reauthentication.
