CVE-2026-2879

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.
