Summary
Vulnerability in github.com/0xJacky/Nginx-UI (CVE-2026-107810). Data can be tampered with by attackers. Exploitable via restore_nginx. Mitigation: upgrade to 1.9.10-0.20260728074146-a467ed652591 or later.
Original description

Summary
An authenticated user who can create and restore a backup can craft a valid backup archive that causes the restore staging process to write attacker-controlled files into the live Nginx configuration path even when both restore_nginx and restore_nginx_ui are set to false.
Details
The restore flow always extracts the outer archive, verifies the manifest, decrypts nginx-ui.zip and nginx.zip, and extracts both inner archives before it decides whether RestoreNginx or RestoreNginxUI should be applied. The zip extractor explicitly allows absolute symlinks when the link target is under nginx.GetConfPath() or nginx.GetModulesPath(). Later regular-file entries are then created with os.OpenFile() on the symlinked path, which follows the symlink and writes into the live path.
Relevant code paths:
- internal/backup/restore.go
- internal/backup/restore.go
- internal/backup/restore.go
- internal/backup/restore.go
- api/backup/restore.go
- api/backup/backup.go
This means the restore trust boundary is broken during extraction. A restore request that explicitly o…
