CVE-2026-101066: DbGate path traversal in archive link creation

CVE-2026-101066 · Severity: high · CVSS 7.3 · Published 2026-09-28

DbGate is a database management tool that allows users to create archive links pointing to directories. A path traversal vulnerability in the archive link creation function allows attackers to read, write, or delete arbitrary files on the server. In the default configuration where authentication is disabled, an unauthenticated attacker can exploit this remotely to execute commands or access sensitive data.

Technologies: DbGate. Vendors: DbGate.

Technical details

The createLink function in packages/api/src/controllers/archive.js validates only the basename of the linkedFolder parameter using assertSafeArchiveName(), allowing attackers to inject directory traversal sequences in the full path that gets written to .link files. The resolveArchiveFolder() function then uses this attacker-controlled path for subsequent archive operations (files/load, files/save, archive/saveText), enabling arbitrary file read/write/delete. The vulnerability is unauthenticated remote when deployed with default anonymous authentication enabled.
