4.2 (Medium) - CVSS:3.0/AV:P/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
Denial of service in langchain-community
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.
