Project: Access code [1] Date: 2025-September-24 Security risk: *Moderately critical* 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Access bypass
Affected versions: <2.0.5 CVE IDs: CVE-2025-10928 Description: This module enables users to sign in with an access code instead of entering user names and passwords. When users are allowed to pick their own access codes, they can guess other users' access codes based on the fact that access codes need to be unique and the system warns if the code of their choice is taken.
This vulnerability is mitigated by the fact that an attacker must have a role with the "change own access code" permission.
Solution: Install the latest version:
* If you use access_code module for Drupal, upgrade to access_code 2.0.5 [3]
