This module provides a standardized solution for building API's so that external clients can communicate with Drupal.

The module doesn't sufficiently sanitize column names provided by the client when they are querying for data and trying to sort it.

This vulnerability is mitigated by the fact that a site must have an "Index" resource enabled and the attacker must know the endpoint's URL.

CVE identifier(s) issued

  • A CVE identifier will be requested, and added upon issuance, in accordance with Drupal Security Team processes.

Versions affected
