DbGate is cross-platform database manager. In versions 7.1.8 and prior, the "unzipDirectory()" function in "packages/api/src/shell/unzipDirectory.js" (line 27) does not validate that extracted file paths stay within the output directory. A malicious ZIP with "../" entries writes files anywhere on the filesystem. In the default Docker deployment, DbGate runs as root and the "none" auth provider issues JWT tokens without credentials via "POST /auth/login", so this is exploitable by any network-adjacent attacker. Version 7.1.9 fixes the issue.
