Missing Authorization in nginx-ui - #VU142602
Published: August 14, 2026
Vulnerability details
The vulnerability allows a remote user to send a fixed-format outbound POST request and obtain limited status and timing information.
The vulnerability exists due to improper access control in the external notification test endpoint when handling authenticated notification test requests without interactive secure-session enforcement. A remote user can trigger a notification test request to a caller-supplied endpoint to send a fixed-format outbound POST request and obtain limited status and timing information.
The target response body is not returned, credentials are not forwarded, and the caller cannot choose an arbitrary HTTP method or arbitrary request body.
