SCA: security update for github.com/0xJacky/Nginx-UI (GHSA-78mf-482w-62qj)
medium Tenable Cloud Security Plugin ID 440701
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.5, all WebSocket endpoints
in nginx-ui use a gorilla/websocket Upgrader with CheckOrigin unconditionally returning true, allowing
Cross-Site WebSocket Hijacking (CSWSH). Combined with the fact that authentication tokens are stored in
browser cookies (set via JavaScript without HttpOnly or explicit SameSite attributes), a malicious webpage
can establish authenticated WebSocket connections to the nginx-ui instance when a logged-in administrator
visits the attacker-controlled page. Version 2.3.5 patches the issue. (CVE-2026-34403)
Solution
Update the github.com/0xJacky/Nginx-UI library and its related packages to version 1.9.10-0.20260316053337-1a9cd29a3082 or later.See Also
