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.
AnalysisAI
Flowise self-hosted instances before 3.1.4 fail to validate the SQLite file path supplied to the SQL Database Chain node, letting any user who can create or edit a chatflow write arbitrary files on the host as the Node.js process. Because the connector creates a database file at whatever path it is given, a traversed path such as ../../ can place attacker-controlled SQLite databases, scripts, or HTML/JS payloads into system directories or the web root, escalating to command execution or stored XSS. …
