Technical details

An incorrect authorization vulnerability exists in the All in One SEO plugin for WordPress due to insufficient permission checks on specific REST API endpoints. Specifically, the 'aioseo/v1/ai/auth' and 'ai/deactivate' routes are accessible to any authenticated user with 'edit_posts' capabilities (Contributor level and above). An attacker with these low-level credentials can send a POST request to overwrite the 'aiAccessToken' or reset the 'isManuallyConnected' state, effectively hijacking or disabling the site's AI integration. The issue is fixed in version 4.9.9.
