An authenticated attacker can add a malicious domain that resolves to an internal or restricted address, trigger a crawl to reach internal services or cloud metadata endpoints like 169.254.169.254, and retrieve the fetched page's title, description, headings, status code and links through the crawl results API, enabling internal network reconnaissance.","state":0,"publishedAt":"2026-10-22T13:20:01.875+00:00","modifiedAt":"2026-10-29T11:38:10.9+00:00","affected":[{"ecosystem":"Vendor product","name":"crawlseo","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"crawlseo\",\n                    \"product\": \"crawlseo\",\n                    \"packageURL\": \"pkg:github/crawlseo/crawlseo\",\n                    \"repo\": \"https://github.com/crawlseo/crawlseo\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.1.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.2.4\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N","score":5.3,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","score":5,"severity":"MEDIUM"}],"references":["https://github.com/crawlseo/crawlseo/commit/76e4e693de0c6b294cf1f60656800e47346f1c28","https://github.com/crawlseo/crawlseo/releases?page=1#release-v0.2.4","https://gist.github.com/mansurmavlankulov/47cb8e183fec39a7afe599d1082a3399","https://www.vulncheck.com/advisories/crawlseo-before-server-side-request-forgery-via-crawler"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115411","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115411","identifiers":["CVE-2026-115411"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
