Prior to 1.1.14, the RecursiveUrlLoader class in @langchain/community is a web crawler that recursively follows links from a starting URL. Its preventOutside option (enabled by default) is intended to restrict crawling to the same site as the base URL. The implementation used String.startsWith() to compare URLs, which does not perform semantic URL validation. An attacker who controls content on a crawled page could include links to domains that share a string prefix with the target, causing the crawler to follow links to attacker-controlled or internal infrastructure. Additionally, the crawler performed no validation against private or reserved IP addresses. A crawled page could include links targeting cloud metadata services, localhost, or RFC 1918 addresses, and the crawler would fetch them without restriction. This vulnerability is fixed in 1.1.14.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:N/A:N","score":4.1,"severity":null}],"references":["https://github.com/langchain-ai/langchainjs/security/advisories/GHSA-gf3v-fwqg-4vh7","https://github.com/langchain-ai/langchainjs/pull/9990","https://github.com/langchain-ai/langchainjs/commit/d5e3db0d01ab321ec70a875805b2f74aefdadf9d","https://github.com/langchain-ai/langchainjs/releases/tag/%40langchain%2Fcommunity%401.1.14"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-6211","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Feb 11, 2026, 9:11:10 PM","dateUpdated":"Feb 12, 2026, 9:14:41 PM"},"relatedAdvisories":[{"id":"WID-SEC-W-2026-0393","title":"LangChain: Mehrere Schwachstellen","vulnerabilityIds":["CVE-2026-26013","CVE-2026-26019"]},{"id":"WID-SEC-W-2026-3046","title":"IBM Concert: Mehrere Schwachstellen","vulnerabilityIds":["CVE-2019-19921","CVE-2021-23337","CVE-2024-3651","CVE-2024-39338","CVE-2024-45590","CVE-2025-13465","CVE-2025-15284","CVE-2025-15599","CVE-2025-22874","CVE-2025-47273","CVE-2025-47907","CVE-2025-52881","CVE-2025-53643","CVE-2025-55184","CVE-2025-58056","CVE-2025-58188","CVE-2025-58189","CVE-2025-61723","CVE-2025-61730","CVE-2025-64649","CVE-2025-64756","CVE-2025-67221","CVE-2025-68121","CVE-2025-68146","CVE-2026-0540","CVE-2026-2327","CVE-2026-23490","CVE-2026-23897","CVE-2026-2391","CVE-2026-23949","CVE-2026-24486","CVE-2026-25528","CVE-2026-25547","CVE-2026-25639","CVE-2026-25990","CVE-2026-26007","CVE-2026-26019","CVE-2026-26996","CVE-2026-27142","CVE-2026-27212","CVE-2026-27699","CVE-2026-27903","CVE-2026-27904","CVE-2026-28684","CVE-2026-29063","CVE-2026-29181","CVE-2026-2950","CVE-2026-31808","CVE-2026-31900","CVE-2026-32274","CVE-2026-32288","CVE-2026-32597","CVE-2026-32630","CVE-2026-32887","CVE-2026-32952","CVE-2026-33186","CVE-2026-33532","CVE-2026-33750","CVE-2026-33814","CVE-2026-33816","CVE-2026-33916","CVE-2026-34043","CVE-2026-34073","CVE-2026-34077","CVE-2026-3520","CVE-2026-35469","CVE-2026-35515","CVE-2026-3627","CVE-2026-39823","CVE-2026-39825","CVE-2026-39826","CVE-2026-39892","CVE-2026-39984","CVE-2026-40175","CVE-2026-40179","CVE-2026-40181","CVE-2026-40190","CVE-2026-40347","CVE-2026-41066","CVE-2026-41182","CVE-2026-41238","CVE-2026-41239","CVE-2026-41240","CVE-2026-41305","CVE-2026-41324","CVE-2026-41425","CVE-2026-41481","CVE-2026-41488","CVE-2026-41602","CVE-2026-41636","CVE-2026-42151","CVE-2026-42154","CVE-2026-42198","CVE-2026-42211","CVE-2026-42338","CVE-2026-42342","CVE-2026-42561","CVE-2026-42577","CVE-2026-43870","CVE-2026-44405","CVE-2026-44431","CVE-2026-44432","CVE-2026-44486","CVE-2026-44487","CVE-2026-44488","CVE-2026-44492","CVE-2026-44494","CVE-2026-44496","CVE-2026-44728","CVE-2026-4539","CVE-2026-45409","CVE-2026-45736","CVE-2026-46625","CVE-2026-4800","CVE-2026-4923","CVE-2026-4926","CVE-2026-7246","CVE-2026-8723"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
