CVE-2026-69255: CWE-94: Improper Control of Generation of Code ('Code Injection') in FlowiseAI Flowise
CVE-2026-69255 is a critical code injection vulnerability in FlowiseAI Flowise prior to version 3.1.3. The issue arises from unsafe interpolation of attacker-controlled CSV data into executable Python code, allowing an authenticated attacker to execute arbitrary OS commands as root within the Flowise container. The vulnerability is fixed in version 3.1.3.
AI Analysis
Technical Summary
FlowiseAI Flowise versions before 3.1.3 contain a code injection vulnerability (CWE-94) in the CSVAgent component. The CSVAgent extracts CSV data using file.split(',').pop() and directly interpolates it into Python code executed by Pyodide without proper validation. The existing denylist validatePythonCodeForDataFrame() only checks later LLM-generated code, not this initial code block. An authenticated attacker can inject a closing quote and arbitrary Python code, leveraging Pyodide's JavaScript bridge to load Node.js child_process and execute arbitrary commands as root inside the container. This vulnerability is resolved in version 3.1.3.
Potential Impact
An authenticated attacker can achieve arbitrary code execution with root privileges inside the Flowise container by exploiting this vulnerability. This can lead to full system compromise of the container environment running Flowise prior to 3.1.3.
Mitigation Recommendations
Upgrade Flowise to version 3.1.3 or later, where this vulnerability is fixed. No other mitigation is documented or recommended by the vendor.
