CVE-2026-54687Network attack vectorHinoki check available

Path traversal via expression-enabled database path

Published Aug 27, 2026 · Updated Aug 27, 2026

Path traversal in DangerBlack n8n-nodes-sqlite3 before 1.0.0 allows remote attackers to read or overwrite files via db_path. The v1 SqliteV1.node.ts definition leaves db_path expression-enabled, so upstream workflow data selects the file that SQLite opens. Exploitation requires a workflow author to map untrusted input into db_path; access is limited to files readable or writable by the n8n process.
