Technical Summary

The Directory Listings WordPress plugin – uListing plugin for WordPress is vulnerable to unauthorized modification of data and PHP Object Injection due to a missing capability check on the stm_listing_ajax AJAX action in all versions up to, and including, 2.1.7. This makes it possible for authenticated attackers, with subscriber-level access and above, to update post meta data and inject PHP Objects that may be unserialized.

Potential Impact

Severity is HIGH (CVSS 8.8). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as High based on remote code execution potential.

Primary risk drivers: remote code execution potential

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
