Stored cross-site scripting via nonce-free settings update
Published Dec 5, 2025 · Updated Apr 8, 2026
Cross-site request forgery in teamdream Dream Gallery 1.0 and earlier allows remote attackers to store malicious scripts through forged requests. The dreampluginsmain AJAX action processes plugin-setting changes without correctly validating a WordPress nonce, allowing attacker-controlled script content to be stored. Exploitation requires a logged-in site administrator to act on an attacker-controlled link or request, after which the stored script executes in affected gallery pages.
