CVE-2025-8492Network attack vector

Unauthenticated data modification via unguarded AJAX actions

Published Sep 11, 2025 · Updated Apr 8, 2026

Missing authorization in Salon Booking System 10.22 and earlier allows remote attackers to modify data through exposed AJAX actions. The AJAX dispatch path reaches the UploadFile handler without checking a WordPress capability before processing attacker-supplied upload data. No account or user interaction is required; successful requests can alter site data and place attacker-supplied files within the handler's restrictions.
