AI Powered Q&A
Can you explain this vulnerability to me?
The GetGenie plugin for WordPress has a vulnerability called Insecure Direct Object Reference (IDOR) in all versions up to and including 4.3.2. This happens because the plugin does not properly validate the 'id' parameter in the 'create()' method of the GetGenieChat REST API endpoint.
An attacker with Author-level access or higher can supply a post ID they control. The method then calls 'wp_update_post()' without checking if the user owns the post or if the post is of the expected type. This allows the attacker to overwrite posts owned by any user, including administrators, by changing the post type and reassigning ownership.
How can this vulnerability impact me? :
This vulnerability allows an authenticated attacker with Author-level access or above to overwrite arbitrary posts owned by any user, including administrators.
The attacker can effectively destroy the original content by changing the post type to 'getgenie_chat' and reassigning the post author to themselves, potentially leading to data loss, content tampering, and unauthorized content control.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
