Quick assessment

Affected
DangerBlack n8n-node-sqlite3
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

n8n-nodes-sqlite3 是一个用于从 n8n 操作本地 SQLite 数据库的节点。在 1.0.0 版本之前， 将 （数据库文件路径）暴露为一个节点参数，允许使用来自上游工作流输入的数据表达式。如果工作流创建者将不可信的输入映射到 ，则远程攻击者可以控制 n8n 进程打开的 SQLite 文件，从而可能遍历到预期数据库位置之外的路径，进而读取、创建或覆盖该进程可访问的文件。此问题已在 1.0.0 版本中修复。

Vulnerability Title
n8n-nodes-sqlite3: Path traversal via user-controlled database file path (db_path parameter)
Source: CVE Program / CVE List V5
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.
