| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
langchain-ai/langchain versions prior to 0.2.5
langchain-community versions prior to 0.2.5
Description
A Denial-of-Service (DoS) issue exists in the
SitemapLoader class due to the parse sitemap method lacking a mechanism to prevent infinite recursion when a sitemap URL refers to itself. This allows for an infinite loop, leading to a crash by exceeding the maximum recursion depth in Python, which can occupy server resources and impact service availability.Recommendations
For langchain-ai/langchain versions prior to 0.2.5, update to version 0.2.5 or later.
For langchain-community versions prior to 0.2.5, update to version 0.2.5 or later.
As a temporary workaround, consider disabling the
parse sitemap method in the SitemapLoader class until a patch is available.Exploit
Fix
