CVE-2026-13444— Langflow is affected by remote code execution, denial of service, path traversal, and exposed credentials due to multiple unauthenticated and insufficiently authorized API endpoints

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 1.0.0版本至1.10.1版本存在配置错误漏洞，该漏洞源于创建具有匹配的Chroma persist_directory和collection_name值的流，允许攻击者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

Vulnerability 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
Source: CVE Program / CVE List V5
Vulnerability Description
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.
