CVE-2024-51996
Symfony has an Authentication Bypass via RememberMe
Impact
### Description When consuming a persisted remember-me cookie, Symfony does not check if the username persisted in the database matches the username attached with the cookie, leading to authentication bypass. ### Resolution The `PersistentRememberMeHandler` class now ensures the submitted username is the cookie owner. The patch for this issue is available [here](https://github.com/symfony/symfony/commit/81354d392c5f0b7a52bcbd729d6f82501e94135a) for branch 5.4. ### Credits We would like to thank Moritz Rauch - Pentryx AG for reporting the issue and Jérémy Derussé for providing the fix.
