CVE-2026-42221: CWE-306: Missing Authentication for Critical Function in 0xJacky nginx-uiCVE-2026-42221 0 CVE-2026-42221 is a high-severity vulnerability in 0xJacky's nginx-ui versions 2.0.0 up to but not including 2.3.8. It allows an unauthenticated remote attacker to claim the initial administrator account during the first-run setup by accessing the public /api/install endpoint without authentication. This leads to permanent takeover of the initial instance by setting the admin email, username, and password. The vulnerability arises because the installation endpoint lacks authentication, and encryption only protects data in transit, not the authorization of the installer. This issue has been fixed in version 2.3. Join the discussion | CVE Database V5 | 05/04/2026, 20:09:37 UTC Added: 05/04/2026, 20:36:24 UTC |
