How to fix?

Upgrade drupal/core to version 6ץ38 or higher.

Overview

Affected versions of drupal/core are vulnerable to Access Restriction Bypass.

The Form API in Drupal 6.x before 6.38 ignores access restrictions on submit buttons, which might allow remote attackers to bypass intended access restrictions by leveraging permission to submit a form with a button that has "#access" set to FALSE in the server-side form definition.
