Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
