CVE-2026-2879: GetGenie <= 4.3.2 - Insecure Direct Object Reference to Authenticated (Author+) Arbitrary Post Overwrite/Deletion

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.

Security readout for executives and security teams

Plain-English summary

CVE-2026-2879 affects the GetGenie WordPress plugin through version 4.3.2. A logged-in user with Author-level access or higher could overwrite posts belonging to others, including administrators. The main business risk is content integrity loss and disruption, not server takeover.

Executive priority

Treat as a moderate-priority content integrity issue. Prioritize sites with many contributors, external authors, or business-critical published content. This is not described as remote unauthenticated compromise, but it can damage or erase visible content workflows.

Technical view

The GetGenieChat REST API create() method lacks ownership and post-type validation for a user-controlled id parameter. If the referenced post exists, it can call wp_update_post(), changing the post type to getgenie_chat and reassigning authorship to the attacker. This is CWE-639 insecure direct object reference.

Likely exposure

Exposure is limited to WordPress sites running GetGenie up to and including 4.3.2 where attackers can authenticate as Author or higher. Sites without untrusted Author-level users have lower practical exposure.

Exploitation context

The CVSS vector is network-accessible, low complexity, low privilege, and no user interaction. The source bundle does not indicate CISA KEV listing or active exploitation. Impact is integrity and availability of WordPress content.

Researcher notes

Evidence points to missing object-level authorization in a REST endpoint. The affected-version statement is clear in the description, but the provided affected metadata is inconsistent and no fixed version is explicitly named in the bundle.

Mitigation direction

  • Check vendor and WordPress plugin guidance for the fixed version or official remediation.
  • Update GetGenie if a fixed release is available from trusted channels.
  • Restrict Author-level and higher accounts to trusted users only.
  • Temporarily disable GetGenie if content integrity risk is unacceptable.
  • Ensure recent WordPress database and content backups are available.

Validation and detection

  • Inventory WordPress sites for GetGenie installations and versions.
  • Flag sites running GetGenie 4.3.2 or earlier.
  • Review Author-level and higher accounts for unnecessary access.
  • Check content history for unexpected author or post_type changes.
  • Confirm remediation by verifying plugin version after update.
