CVE-2026-54687: Dangerblack N8n Node Sqlite3: Information disclosure

CVE-2026-54687 is rated critical with a CVSS v3.1 base score of 9.8 and NVD lists Dangerblack N8n Node Sqlite3 as the affected product. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability description

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.

Underlying weakness

CWE-22: Improper Limitation of a Pathname to a Restricted Directory

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.

Affected products

  • Dangerblack N8n Node Sqlite3: 1.0.0
