DescriptionGitHub Advisory

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.0.13, unauthenticated users can inject arbitrary values into internal database fields when creating leads. This issue has been patched in version 3.0.13.

Executive ViewAI

Why It Matters

Flowise versions 3.0.13 and earlier contain a vulnerability allowing attackers to modify object attributes without proper authorization, potentially leading to unauthorized data manipulation or system compromise. Organizations running affected versions face immediate risk, particularly if Flowise instances are internet-facing or process sensitive data.

Business Impact: High
Compensating Controls

Implement Web Application Firewall (WAF) rules to detect and block requests attempting object attribute modification; restrict network access to Flowise instances using firewall rules and VPN-only access; disable dynamic object attribute modification features if available in configuration; enforce strong authentication and multi-factor authentication for all administrative access; increase logging and monitoring for suspicious API calls and attribute changes; run Flowise with minimal required privileges and in isolated network segments away from production systems.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
