Administrator-session script execution via unescaped stored label
Published Jul 30, 2026 · Updated Jul 30, 2026
Stored XSS in GoodLayers Tour Master before 5.4.8 allows remote attackers to execute JavaScript in an administrator's session. The filter-management handler stores a custom-filter label from a request parameter without a nonce check, and the filter admin page renders the saved label without output escaping. Exploitation requires a logged-in administrator to open an attacker-controlled page, which submits the request and reaches script execution in the WordPress admin area.
