Summary
CodeIgniter4 Potential Session Handlers Vulnerability
Details

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.
