SCA: security update for github.com/0xJacky/Nginx-UI (GHSA-g9w5-qffc-6762)

critical Tenable Cloud Security Plugin ID 438415

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-27944)
