Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Packagist | codeigniter4/framework | < 4.2.11 | 4.2.11 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
