What is CVE-2026-54687?
CVE-2026-54687 is a medium-severity path traversal vulnerability in DangerBlack n8n-node-sqlite3, published on 27 Aug 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official 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.
Weakness: CWE-22
