    DRUPAL-CONTRIB-2026-296

    Published: 4 Nov 2026Last Modified: 4 Nov 2026

    Summary:

    Details: This module introduces an OAuth 2.0 authorization server, which can be configured to protect your Drupal instance with access tokens, or allow clients to request new access tokens and refresh them. The module doesn't sufficiently restrict access to consumer configuration. Users who can create or edit consumers can potentially configure malicious consumers and obtain tokens with additional privileges. This can allow them to access the site as another user, up to full administrative access. This vulnerability is mitigated by the fact that an attacker must have a role with the *Add consumer entities* or *Update own consumer entities* permissions.
