CVE-2024-2965 / GHSA-3hjh-jh2h-vrg6 · severity: medium · CVSS 4.2 · PyPI
Affected
langchain>= 0, < 0.2.5 → fixed in 0.2.5
Details
Denial of service in SitemapLoader Document Loader in the langchain-community package, affecting versions below 0.2.5. 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.
