CVE-2026-27944
Nginx-UI Vulnerable to Unauthenticated Backup Download with Encryption Key Disclosure
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon GHSA.
Description
Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.3, the /api/backup endpoint is accessible without authentication and discloses the encryption keys required to decrypt the backup in the X-Backup-Security response header. This allows an unauthenticated attacker to download a full system backup containing sensitive data (user credentials, session tokens, SSL private keys, Nginx configurations) and decrypt it immediately. This issue has been patched in version 2.3.3.
