Detailsinfo

A vulnerability was found in roxnor GetGenie Plugin up to 4.3.2 on WordPress. It has been declared as problematic. Affected by this vulnerability is the function create of the component REST API Endpoint. The manipulation of the argument id with an unknown input leads to a authorization vulnerability. The CWE definition for the vulnerability is CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. As an impact it is known to affect integrity, and availability. The summary by CVE is:

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.

The weakness was disclosed by Kazuma Matsumoto. It is possible to read the advisory at wordfence.com. This vulnerability is known as CVE-2026-2879 since 02/20/2026.
