Title

IBM Langflow OSS配置错误漏洞

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存在配置错误漏洞，该漏洞源于创建具有匹配的Chroma persist_directory和collection_name值的流，攻击者可利用该漏洞通过访问另一个用户的私有向量文档，并在工作流输出中接收受害者精确内容，同时还可以通过插入文档污染受害者集合。

CVE-2026-13444 (GCVE-0-2026-13444)

Vulnerability from cvelistv5 – Published: 2026-07-30 18:38 – Updated: 2026-07-30 19:21

Title

Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints

Summary

IBM Langflow OSS 1.0.0 through 1.10.1 can allow an attacker to access another user's private vector documents by creating their own flow with matching Chroma persist_directory and collection_name values. The attacker receives exact victim content in their workflow output despite having no authorization to read the victim's flow. Additionally, the attacker can pollute the victim's collection by inserting their own documents into the shared namespace.
