AI Analysis
Technical Summary
The Rate Star Review Vote – AJAX Reviews, Votes, Star Ratings WordPress plugin (up to version 1.6.4) contains a missing authorization vulnerability (CWE-862) in its vwrsr_review() AJAX handler. The handler only checks if a user is logged in but lacks capability checks and nonce verification. When the 'form' parameter is 'update', the handler accepts a user-supplied 'rating_id' GET parameter as a post ID and passes it to wp_update_post() and update_post_meta() without proper authorization. This allows authenticated users with Subscriber-level privileges or higher to modify arbitrary posts' title, content, author (to the attacker's user ID), post type, and metadata, effectively enabling full post content takeover.
Potential Impact
Authenticated attackers with Subscriber-level access or higher can modify arbitrary posts and pages on the affected WordPress site. They can change critical post attributes including title, content, author, post type, and metadata. This could lead to unauthorized content manipulation, defacement, or misinformation on the site. The CVSS score is 4.3 (medium severity), reflecting the limited scope to authenticated users but significant impact on integrity.
Mitigation Recommendations
Patch status is not yet confirmed — no official fix or patch links are provided. Users should monitor the vendor's advisory for updates. Until a patch is available, restrict plugin usage to trusted users only and consider disabling or removing the plugin if possible. Implement additional access controls or custom code to validate user capabilities and nonce verification for AJAX requests related to post updates.
