Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Drupal/drupal, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Drupal 8.x before 8.1.10 does not properly check for "Administer comments" permission, which allows remote authenticated users to set the visibility of comments for arbitrary nodes by leveraging rights to edit those nodes.
