 3    cve: CVE-2024-2965
 4    summary: Denial of service in langchain-community
 5    details: |
 6      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.
 7    cvss: CVSS:3.0/AV:P/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
 8    severity: MEDIUM
 9    security_advise: |
10      1. Upgrade to langchain-community>=0.2.5
11      2. Review and update the `parse_sitemap` method to prevent infinite recursion
12      3. Monitor server logs for unusual activity that may indicate a DoS attempt
13  rule: version < "0.2.5"
