SQLite Database Path Traversal in Flowise

Publication date: 2026-09-15

Last updated on: 2026-09-15

Assigner: VulnCheck

Description
Flowise versions before 3.1.4 fail to validate file paths in the SQL Database Chain node when connecting to SQLite databases, allowing authenticated attackers to write arbitrary files. Attackers can write malicious SQLite databases to system directories or inject files into the web root to execute commands or perform stored XSS attacks.

Executive Summary

Flowise versions before 3.1.4 do not properly validate file paths in the SQL Database Chain node when connecting to SQLite databases. This allows authenticated attackers to write arbitrary files to the system. Attackers could place malicious SQLite databases in system directories or inject files into the web root to execute commands or perform stored cross-site scripting (XSS) attacks.

Detection Guidance

Check Flowise versions before 3.1.4 by running commands like 'npm list -g flowise' or 'flowise --version'. Inspect SQLite database connections in the SQL Database Chain node for improper file path validation. Look for unexpected files in system directories or web root.

Impact Analysis

This vulnerability allows attackers with authentication to write files anywhere on the system. This could lead to command execution, data theft, or defacement of the web application. Attackers might also plant backdoors or malware in the web root to compromise users visiting the site.

Compliance Impact

This vulnerability could lead to unauthorized data access, modification, or exfiltration, violating GDPR and HIPAA requirements for data protection and integrity. Non-compliance may result in legal penalties, fines, or reputational damage due to breaches of confidentiality and security controls.

Mitigation Strategies

Upgrade Flowise to version 3.1.4 or later immediately. Review and restrict file write permissions in system directories and web root. Audit existing SQLite database connections for suspicious file paths or unauthorized writes.
