CVE-2026-69254: CWE-94: Improper Control of Generation of Code ('Code Injection') in FlowiseAI Flowise
CVE-2026-69254 is a critical code injection vulnerability in FlowiseAI's Flowise prior to version 3.1.3. It allows an authenticated attacker with limited privileges to execute arbitrary system commands as root by exploiting improper control over JavaScript code execution options. The flaw arises from the executeJavaScriptCode() function merging caller-provided NodeVM options over default security settings, enabling escalation to full system command execution. This issue is fixed in Flowise version 3.1.3.
AI Analysis
Technical Summary
FlowiseAI Flowise versions before 3.1.3 contain a CWE-94 code injection vulnerability in the executeJavaScriptCode() function. The function accepted user-supplied nodeVMOptions that override default NodeVM security configurations. An authenticated attacker able to reach the node-custom-functions route can invoke executeJavaScriptCode() with nodeVMOptions.require.builtin set to allow all built-in Node.js modules, including child_process. This enables arbitrary system command execution as root on the Flowise server. The vulnerability is resolved in version 3.1.3.
Potential Impact
An authenticated attacker with limited privileges can escalate to execute arbitrary system commands as root on the Flowise server, potentially leading to full system compromise. The vulnerability has a CVSS 4.0 score of 9.4 (critical), indicating high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade Flowise to version 3.1.3 or later, where this vulnerability is fixed. No other mitigation or temporary workaround is documented. Patch status is confirmed fixed in 3.1.3.
