Project: Key auth [1]
Date: 2026-September-09
Security risk: *Moderately critical* 13 ∕ 25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Access bypass

Affected versions: <2.2.4
CVE IDs: CVE-2026-87940
Description: 
This module enables you to add key-based authentication on a per-user
basis.

The module doesn't cache per user, potentially allowing an attacker to view
another user's authentication keys, if the attacker has the same permissions.

This vulnerability is mitigated by the fact that the site must have the
dynamic_page_cache module enabled.

Solution: 
Install the latest version:

 * If you use the Key Auth module, upgrade to Key auth 2.2.4 [3].
