CVE-2026-34403: CWE-1385: Missing Origin Validation in WebSockets in 0xJacky nginx-uiCVE-2026-34403 0 CVE-2026-34403 is a medium severity vulnerability in 0xJacky's nginx-ui prior to version 2. 3. 5. The issue arises because all WebSocket endpoints use a gorilla/websocket Upgrader with CheckOrigin always returning true, which allows Cross-Site WebSocket Hijacking (CSWSH). Since authentication tokens are stored in browser cookies without HttpOnly or SameSite attributes, a malicious webpage can establish authenticated WebSocket connections if an administrator visits it. Version 2. 3. 5 addresses this vulnerability. Join the discussion | CVE Database V5 | 04/20/2026, 20:16:47 UTC Added: 04/20/2026, 21:01:19 UTC |
