From 2.3.8 until 2.5.0, an authenticated administrator with an active secure session can submit attacker-controlled portable backup key material and a matching manifest to POST /api/restore. The restore flow trusts the supplied key, decrypts attacker-controlled contents, and replaces the live app.ini, including protected nginx command settings such as TestConfigCmd. Triggering POST /api/nginx/test then executes the restored command in the Nginx UI runtime context, affecting confidentiality, integrity, and availability. 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-2026-107806)\n\nAffected packages:\n\n- `github.com/0xJacky/Nginx-UI >= 1.9.10-0.20260421071512-7864e378f5cf, < 1.9.10-0.20260728074146-a467ed652591`\n\nPatched in:\n\n- `github.com/0xJacky/Nginx-UI 1.9.10-0.20260728074146-a467ed652591`\n\nSource: https://github.com/advisories/GHSA-p393-cf76-4jmr","depth":"abyssal","depthScore":64,"depthScoreParts":{"impact":51.7,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":221189,"id":"CVE-2026-107806","ts":1792030807962,"field":"cvss","old":null,"new":"9.4"},{"seq":219349,"id":"CVE-2026-107806","ts":1791806427939,"field":"exploit_available","old":"false","new":"true"},{"seq":218620,"id":"CVE-2026-107806","ts":1791580430494,"field":"severity","old":"none","new":"critical"}]}
