Vulnerability from cnvd - Published: 2026-07-15

Title

IBM Langflow OSS代码注入漏洞

Description

IBM Langflow OSS是美国IBM公司的一个开源的低代码可视化AI工作流构建工具，它让开发者能通过拖拽组件的方式快速搭建、部署和迭代AI智能体与RAG应用，同时支持用Python进行深度定制以集成企业系统。 IBM Langflow OSS存在代码注入漏洞，攻击者可利用该漏洞读取Langflow进程所有机密、读取和修改数据库中的流程、对话、消息、文件上传和已保存组件、连接内部服务、滥用云元数据端点、横向移动到其他租户，并通过修改公共流中的tool_code实现持久化。

CVE-2026-10134 (GCVE-0-2026-10134)

Vulnerability from cvelistv5 – Published: 2026-06-30 19:56 – Updated: 2026-07-01 17:27

Title

Unauthenticated Server-Side RCE via PythonCodeStructuredTool in Public Flows

Summary

IBM Langflow OSS 1.0.0 through 1.9.3 allows an attacker to read every secret available to the Langflow process, read and modify every flow, conversation, message, file upload, and saved component in the Langflow database, can connect to internal services, abuse cloud metadata endpoints, laterally move to other tenants on the same Langflow instance, and Establish persistence by modifying the public flow's `tool_code` so normal `/api/v1/build/...` calls by any user re-execute attacker code at each build.
