CVE-2025-6985 (CNNVD-202510-769)
中文标题:
langchain-text-splitters 代码问题漏洞
英文标题:
XXE Vulnerability in langchain-ai/langchain
漏洞描述
中文描述:
langchain-text-splitters是LangChain开源的一个Python包。 langchain-text-splitters 0.3.8版本存在代码问题漏洞，该漏洞源于HTMLSectionSplitter类允许使用任意XSLT样式表，可能导致XML外部实体攻击，攻击者可读取任意本地文件或执行外部HTTP请求。
英文描述:
The HTMLSectionSplitter class in langchain-text-splitters version 0.3.8 is vulnerable to XML External Entity (XXE) attacks due to unsafe XSLT parsing. This vulnerability arises because the class allows the use of arbitrary XSLT stylesheets, which are parsed using lxml.etree.parse() and lxml.etree.XSLT() without any hardening measures. In lxml versions up to 4.9.x, external entities are resolved by default, allowing attackers to read arbitrary local files or perform outbound HTTP(S) fetches. In lxml versions 5.0 and above, while entity expansion is disabled, the XSLT document() function can still read any URI unless XSLTAccessControl is applied. This vulnerability allows remote attackers to gain read-only access to any file the LangChain process can reach, including sensitive files such as SSH keys, environment files, source code, or cloud metadata. No authentication, special privileges, or user interaction are required, and the issue is exploitable in default deployments that enable custom XSLT.
