CVE-2026-2879
CWE-639Published: March 13, 2026· Updated: Mar 16, 2026
Official Description
The GetGenie plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.2. This is due to missing validation on the `id` parameter in the `create()` method of the `GetGenieChat` REST API endpoint. The method accepts a user-controlled post ID and, when a post with that ID exists, calls `wp_update_post()` without verifying that the current user owns the post or that the post is of the expected `getgenie_chat` type. This makes it possible for authenticated attackers, with Author-level access and above, to overwrite arbitrary posts owned by any user — including Administrators — effectively destroying the original content by changing its `post_type` to `getgenie_chat` and reassigning `post_author` to the attacker.
Technical Analysis
CVE-2026-2879 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
