CVE-2026-14524
CriticalCVSS 9.1Summary
The ProSolution WP Client plugin for WordPress up to version 2.0.8 contains an arbitrary file deletion vulnerability. Insufficient file path validation in the proSol_fileDeleteProcess function allows unauthenticated attackers to delete arbitrary files on the server, potentially leading to remote code execution.
Risk Assessment
An attacker can delete critical files such as wp-config.php, leading to complete loss of control over the site and potential remote code execution.
Recommendation
Update the plugin to the latest patched version. Additionally, restrict access to file upload and deletion functions and monitor server logs.
Original NVD description (English source)
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.
