Summary

CVE-2026-41138 is a high-severity Code Injection (CWE-94) vulnerability in Flowiseai Flowise. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 46th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as LLM Application Platforms; in the LLM/Generative AI Risks risk domain.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2026-41138 is a remote code execution vulnerability in Flowise, an open-source drag-and-drop user interface for building customized large language model (LLM) flows. The issue affects versions prior to 3.1.0 and resides in the AirtableAgent.ts component, where a lack of input verification allows malicious user input supplied to the "question" parameter in a prompt template to be directly reflected into executed Python code via Pandas without sanitization. This CWE-94 (code injection) flaw carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for arbitrary code execution.

An attacker with low-privilege access (PR:L), such as an authenticated user, can exploit this over the network with low complexity and no user interaction required. By crafting malicious input that injects Python code through the unsanitized prompt parameter, the attacker achieves remote code execution on the server, potentially compromising confidentiality, integrity, and availability with high impact—enabling full system takeover, data exfiltration, or further lateral movement.

The vulnerability is addressed in Flowise version 3.1.0, as detailed in the official security advisory at https://github.com/FlowiseAI/Flowise/security/advisories/GHSA-f228-chmx-v6j6. Security practitioners should prioritize upgrading to 3.1.0 or later and review access controls for AirtableAgent usage.

Flowise's role in LLM orchestration makes this vulnerability particularly relevant for AI/ML deployments, where untrusted inputs could propagate through agentic workflows. No public evidence of real-world exploitation has been reported as of the CVE publication on 2026-04-23.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
