CVE-2026-14524: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in prosolution ProSolution WP Client
The ProSolution WP Client plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the proSol_fileDeleteProcess function in all versions up to, and including, 2.0.8. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). An attacker must first call the proSol_fileUploadModalProcess handler to poison their own session with a path-traversal key, then call proSol_fileDeleteProcess with that key as the filename parameter; both steps require only the publicly exposed frontend nonce.
AI Analysis
Technical Summary
CVE-2026-14524 is a path traversal vulnerability (CWE-22) in the ProSolution WP Client plugin for WordPress. The flaw arises from inadequate validation of file paths in the proSol_fileDeleteProcess function, allowing unauthenticated attackers to delete arbitrary files on the server. Exploitation involves first calling proSol_fileUploadModalProcess to inject a path-traversal key into the session, then invoking proSol_fileDeleteProcess with this key as the filename parameter. Both steps require only a publicly exposed frontend nonce, making the attack feasible without authentication. Deleting critical files like wp-config.php can lead to remote code execution. The vulnerability affects all versions up to and including 2.0.8. No official patch or remediation guidance is currently available.
Potential Impact
An attacker can delete arbitrary files on the server hosting the WordPress site by exploiting this vulnerability. This can lead to denial of service or remote code execution if critical files such as wp-config.php are deleted. The vulnerability requires no authentication and has a low attack complexity, making it highly impactful and critical in severity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected plugin and monitor for suspicious activity. Consider disabling or removing the ProSolution WP Client plugin if possible to prevent exploitation.
