Stored XSS in WPChill Image Photo Gallery Final Tiles Grid 3.6.8 and earlier allows remote authenticated users to inject scripts via Custom scripts. The gallery renderer in lib/gallery-class.php places the saved Custom scripts value into generated page output without sufficient sanitization or context-appropriate escaping. Author-level access is required to save the payload, and the injected script executes whenever a user opens the affected gallery page.
