Detailsinfo

A vulnerability classified as critical has been found in DangerBlack n8n-node-sqlite3 up to 0.x. Affected is some unknown functionality of the file nodes/SqliteNode/v1/SqliteV1.node.ts of the component SqliteNode. The manipulation of the argument db_path with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

n8n-nodes-sqlite3 is a node for operating a local SQLite database from n8n. Prior to 1.0.0, nodes/SqliteNode/v1/SqliteV1.node.ts exposes the db_path database file path as a node parameter that permits data expressions from upstream workflow input. A workflow author who maps untrusted input to db_path can allow a remote attacker to select which SQLite file the n8n process opens, enabling traversal outside the intended database location and potentially reading, creating, or overwriting files accessible to the process. This issue is fixed in version 1.0.0.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-54687 since 06/16/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

Upgrading to version 1.0.0 eliminates this vulnerability.
