CSRF in Vtenext
CVE-2025-71454
vtenext before 25.02.2 contains a cross-site request forgery protection bypass because csrf_check() in include/utils/VteCsrf.php skips __csrf_token validation for non-POST requests. Attackers can induce a logged-in user to open a crafted link sending state-changing GET requests, which handlers read from $_REQUEST, performing actions as that user.
