RestWS - Moderately Critical - Information Disclosure - SA-CONTRIB-2017-024

RestWS makes Drupal Entity data available in a REST API.

The module doesn’t sufficiently check for access to properties when filtering queries.

This vulnerability is mitigated by the fact that an attacker must have a role that allows them to access an entity type with access-controlled properties. And the attacker can only query on the property equalling a value supplied by the attacker.

CVE identifier(s) issued

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

Versions affected
