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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-107809)\n\nAffected packages:\n\n- `github.com/0xJacky/Nginx-UI >= 1.9.10-0.20250517140552-daee3ac7ade1, < 1.9.10-0.20260728074433-a3999bd78a3b`\n\nPatched in:\n\n- `github.com/0xJacky/Nginx-UI 1.9.10-0.20260728074433-a3999bd78a3b`\n\nSource: https://github.com/advisories/GHSA-33rr-wq23-g6gg","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
