CVE-2023-2173Network attack vector

Arbitrary post deletion via unchecked object authorization

Published Aug 31, 2023 · Updated Apr 8, 2026

Insecure direct object reference in LearningTimes BadgeOS 3.7.1.6 and earlier allows remote authenticated users to delete arbitrary posts. Four AJAX deletion handlers accept a user-controlled post identifier and delete the referenced post without validating authorization for that object. Subscriber-level access is sufficient, and the bounded impact is unauthorized deletion of WordPress post content.
