CVE-2024-2965 Information

Description

A Denial-of-Service (DoS) vulnerability exists in the SitemapLoader class of the langchain-ai/langchain repository affecting all versions. The parse_sitemap method responsible for parsing sitemaps and extracting URLs lacks a mechanism to prevent infinite recursion when a sitemap URL refers to the current sitemap itself. This oversight allows for the possibility of an infinite loop leading to a crash by exceeding the maximum recursion depth in Python. This vulnerability can be exploited to occupy server socket/port resources and crash the Python process impacting the availability of services relying on this functionality.
