CodeIgniter4 Potential Session Handlers Vulnerability
### Impact When an application uses (1) multiple session cookies (e.g., one for user pages and one for admin pages) and (2) a session handler is set to `DatabaseHandler`, `MemcachedHandler`, or `RedisHandler`, then if an attacker gets one session cookie (e.g., one for user pages), they may be able to access pages that require another session cookie (e.g., for admin pages). ### Patches Upgrade to version 4.2.11 or later. ### Workarounds - Use only one session cookie. ### References - https://codeigniter4.github.io/userguide/libraries/sessions.html#session-drivers ### For more information If you have any questions or comments about this advisory: * Open an issue in [codeigniter4/CodeIgniter4](https://github.com/codeigniter4/CodeIgniter4/issues) * Email us at [SECURITY.md](https://github.com/codeigniter4/CodeIgniter4/blob/develop/SECURITY.md)
