Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, AuthRequired accepts a browser-managed token cookie as an API credential after the front end stores the JWT in that cookie. Because management endpoints do not universally require a CSRF token or perform Origin or Referer validation, a remote attacker can induce a logged-in administrator's browser to submit authenticated cross-site state-changing requests, including POST /api/configs. The attack requires an administrator account without OTP/Passkey or a target endpoint that does not require secure-session proof. The attacker cannot read the cross-origin response but can modify Nginx configuration, trigger reloads, or invoke other management operations reachable with the victim's session. This issue is fixed in version 2.5.0.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
