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."}],"affected":[{"vendor":"langchain-ai","product":"langchain-ai/langchain","versions":[{"version":"unspecified","lessThan":"0.2.5","status":"affected","versionType":"custom"}]}],"references":[{"url":"https://huntr.com/bounties/90b0776d-9fa6-4841-aac4-09fde5918cae"},{"url":"https://github.com/langchain-ai/langchain/commit/73c42306745b0831aa6fe7fe4eeb70d2c2d87a82"}],"metrics":[{"cvssV3_0":{"version":"3.0","attackComplexity":"HIGH","attackVector":"PHYSICAL","availabilityImpact":"HIGH","confidentialityImpact":"NONE","integrityImpact":"NONE","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.0/AV:P/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":4.2,"baseSeverity":"MEDIUM"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-674 Uncontrolled Recursion","cweId":"CWE-674"}]}],"source":{"advisory":"90b0776d-9fa6-4841-aac4-09fde5918cae","discovery":"EXTERNAL"}},"adp":[{"affected":[{"vendor":"langchain","product":"langchain","cpes":["cpe:2.3:a:langchain:langchain:*:*:*:*:*:*:*:*"],"defaultStatus":"unknown","versions":[{"version":"0","status":"affected","lessThan":"*","versionType":"custom"}]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-06-07T13:30:27.318825Z","id":"CVE-2024-2965","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-07T19:03:21.881Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-01T19:32:42.613Z"},"title":"CVE Program Container","references":[{"url":"https://huntr.com/bounties/90b0776d-9fa6-4841-aac4-09fde5918cae","tags":["x_transferred"]}]}]}}
