CVE-2026-9196— Langflow OSS is affected by arbitrary code execution in component generation, validation, and custom component handling

Quick assessment

Affected
IBM Langflow OSS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

IBM Langflow OSS是美国IBM公司的一款可视化构建AI工作流的低代码工具平台。 IBM Langflow OSS 1.0.0版本至1.10.3版本存在代码注入漏洞，该漏洞源于对LLM生成组件处理不当，在验证期间用户批准之前执行模型生成的Python代码，可能导致攻击者以Langflow后端进程权限触发副作用，如出站网络访问、文件系统交互或数据泄露。

Vulnerability Title
Langflow OSS is affected by arbitrary code execution in component generation, validation, and custom component handling
Source: CVE Program / CVE List V5
Vulnerability Description
IBM Langflow OSS 1.0.0 through 1.10.3 could allow an authenticated attacker to execute unintended code during Agentic Assistant validation due to improper handling of LLM‑generated components. The application executes model‑generated Python code in the backend during validation prior to user approval, which may allow an attacker to trigger side effects such as outbound network access, file system interaction, or data exfiltration with the privileges of the Langflow backend process.
