DescriptionCVE.org

The Classified Listing - AI-Powered Classified ads & Business Directory Plugin plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 5.3.10. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to add arbitrary notes to any order and trigger unsolicited notification and moderation emails to listing owners without administrative authorization.

AnalysisAI

Authenticated attackers with subscriber-level access can add arbitrary notes to any order in the Classified Listing - AI-Powered Classified ads & Business Directory Plugin (all versions up to 5.3.10) due to missing authorization checks, triggering unsolicited notification and moderation emails to listing owners. The plugin fails to verify user permissions before allowing note creation, enabling privilege escalation within WordPress installations where subscriber accounts exist. No public exploit code or active exploitation has been identified at the time of analysis.

Technical ContextAI

The vulnerability exists in the plugin's note-addition functionality, specifically within the Comments.php and ListingAdminAjax.php controllers, which handle user-triggered actions without proper authorization verification. The root cause is classified as CWE-862 (Missing Authorization), indicating the plugin does not implement role-based access control checks before executing order-note operations. The affected component processes Ajax requests and comment hooks that should be restricted to order owners or administrators but are instead accessible to any authenticated user with subscriber-level permissions or above. WordPress uses the current_user_can() function to verify capabilities; the plugin's failure to use such checks allows subscriber accounts to bypass intended access restrictions and manipulate order data and notifications.

RemediationAI

Update the Classified Listing plugin to the latest patched version immediately; plugin developers are expected to release version 5.3.11 or later with proper authorization checks. No specific fixed version is confirmed in the provided data, so contact the plugin vendor (TechLabPro1) or monitor the plugin repository for security updates. Until a patch is released, administrators should restrict subscriber-level access to users who are fully trusted, use WordPress role-management plugins to prevent subscriber account creation, or temporarily disable the classified listings feature if not critical to operations. Audit all orders created since the plugin was installed to identify any unauthorized notes added by non-admin accounts. Review WordPress access logs and plugin activity logs for evidence of exploitation. As a temporary workaround, use custom code to enforce authorization checks in the Comments.php and ListingAdminAjax.php controllers, but this is not a long-term solution and may break on plugin updates.
