Vulnerability Title
DbGate: Zip Slip in archive/unzip allows arbitrary file write leading to RCE
Source: CVE Program / CVE List V5
Vulnerability Description
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.
