Unauthorized state changes via tokenless request dispatch
Published Aug 4, 2026 · Updated Aug 4, 2026
Cross-site request forgery in RackTables 0.22.0 and earlier allows remote attackers to modify objects through authenticated browser sessions. The common form generator omits anti-CSRF tokens, while the redirect and AJAX dispatchers invoke state-changing handlers without validating a token or request origin. Exploitation requires an authenticated victim with permission for the chosen operation to visit attacker-controlled content; the published PoC changes a port reservation comment.
