CVE-2026-17626— Langflow is affected by security vulnerabilities in Model Context Protocol features

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版本存在权限许可和访问控制问题漏洞，该漏洞源于对危险的Docker卷挂载和设备映射参数过滤不完整，可能导致经过身份验证的攻击者通过基于Docker的MCP服务器读取、修改或暴露敏感主机文件。
