CVE-2026-14524Network attack vectorHinoki check available

Arbitrary file deletion via poisoned session path

Published Aug 16, 2026 · Updated Aug 16, 2026

Arbitrary file deletion in ProSolution WP Client 2.0.8 and earlier allows remote attackers to delete server files through AJAX requests. The proSol_fileUploadModalProcess handler accepts a traversal-bearing newfilename into session state, and proSol_fileDeleteProcess later passes the selected stored path to unlink without confining it to uploads/prosolwpclient. The public portal nonce is sufficient for both requests; deleting wp-config.php interrupts the site and can enable remote code execution.
