CVE-2025-71454 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.9 (medium) and affects vtenext; fixed in 25.02.2.

## Affected

- vtenext: fixed in 25.02.2

## Description

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.
