CVE-2026-41264: CWE-184: Incomplete List of Disallowed Inputs in FlowiseAI Flowise
FlowiseAI Flowise versions prior to 3.1.0 contain a critical remote code execution vulnerability (CVE-2026-41264) in the CSV_Agents class. This vulnerability is due to insufficient sandboxing of Python scripts generated by the LLM, which allows unauthenticated attackers to execute arbitrary Python code with the privileges of the Flowise server user. The issue is fixed in version 3.1.0.
AI Analysis
Technical Summary
CVE-2026-41264 is a critical remote code execution vulnerability affecting FlowiseAI Flowise versions before 3.1.0. The vulnerability stems from an incomplete list of disallowed inputs (CWE-184) in the CSV_Agents class, resulting in insufficient sandboxing of Python scripts generated by the language model. This flaw enables unauthenticated attackers to execute arbitrary Python code on the server with the same privileges as the Flowise process. The vulnerability is resolved in Flowise version 3.1.0.
Potential Impact
An unauthenticated attacker can remotely execute arbitrary Python code on the Flowise server, potentially leading to full compromise of the server environment with the privileges of the Flowise user. This can result in unauthorized access, data theft, or further system compromise.
Mitigation Recommendations
Upgrade FlowiseAI Flowise to version 3.1.0 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is documented. Patch status is confirmed by the vendor stating the fix is in version 3.1.0.
