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.\n\n## Affected packages\n\n- `langchain-community < 0.2.5`\n- `langchain < 0.2.5`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `langchain-community 0.2.5`\n- `langchain 0.2.5`","depth":"sunlit","depthScore":23,"depthScoreParts":{"impact":23.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
