CVE-2026-46715 · Flask-Security-Too OAuth reauthentication freshness bypass via cross- user OAuth identity acceptance
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Flask-Security-Too allows users to add security features to their Flask applicationa. Version 5.8.0's OAuth reauthentication flow can mark a session as fresh after verifying an OAuth account that belongs to a different user. If an attacker can operate an already-authenticated but stale victim session, they can complete OAuth verification using their own OAuth identity. The victim session is then treated as recently reauthenticated, allowing freshness-protected account actions to proceed. Version 5.8.1 contains a fix for this issue.
