Infinite Recursion Vulnerability in langchain-ai/langchain Affects All Versions
CVE-2024-2965
4.7MEDIUM
What is CVE-2024-2965?
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.
