Technical Summary

The WordPress File Upload plugin for WordPress is vulnerable to Remote Code Execution, Arbitrary File Read, and Arbitrary File Deletion in all versions up to, and including, 4.24.15 via the 'wfu_file_downloader.php' file. This is due to lack of proper sanitization of the 'source' parameter and allowing a user-defined directory path. This makes it possible for unauthenticated attackers to execute code on the server.

Potential Impact

Severity is CRITICAL (CVSS 9.8). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as Very High based on remote code execution potential, low-bar exploit prerequisites.

Primary risk drivers: remote code execution potential, low-bar exploit prerequisites

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.
