Administrative takeover via CSRF-exempt GET requests
Published Jul 13, 2026 · Updated Jul 13, 2026
Cross-site request forgery in Rejetto HFS 3.0.0 through 3.2.0 allows remote attackers to perform administrative actions via crafted URLs. The API router accepts state-changing operations through GET requests, while the anti-CSRF middleware skips its header requirement for every GET request. Exploitation requires a logged-in administrator to navigate to the URL, except that default localhost administration permits unauthenticated requests originating on the server, enabling account creation, configuration changes, and code execution.
