{"id":"CVE-2026-112363","summary":"Crawl4AI 0.8.7 through 0.9.5 SSRF Bypass via SSLCertificate.from_url URL Userinfo","details":"Crawl4AI from 0.8.7 through 0.9.5 contains a server-side request forgery vulnerability in the Docker API server that allows unauthenticated attackers to bypass destination checks via URL userinfo parsing differences. Attackers can set fetch_ssl_certificate=true with crafted userinfo URLs so SSLCertificate.from_url connects to internal hosts on port 443, probing reachability and leaking certificate details.","modified":"2026-10-20T02:45:29.358778635Z","published":"2026-10-19T15:28:59.792Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112363.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112363.json"},{"type":"PACKAGE","url":"https://github.com/unclecode/crawl4ai"},{"type":"ARTICLE","url":"https://github.com/unclecode/crawl4ai/blob/v0.9.5/crawl4ai/async_crawler_strategy.py"},{"type":"ARTICLE","url":"https://github.com/unclecode/crawl4ai/blob/v0.9.5/crawl4ai/ssl_certificate.py"},{"type":"ARTICLE","url":"https://github.com/unclecode/crawl4ai/blob/v0.9.5/deploy/docker/utils.py"},{"type":"FIX","url":"https://github.com/unclecode/crawl4ai/pull/2304"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112363"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/crawl4ai-0.8.7-through-0.9.5-ssrf-bypass-via-sslcertificate-from-url-url-userinfo"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/unclecode/crawl4ai","events":[{"introduced":"7b280d36b150b544bf0994285b4755dca18c2149"},{"last_affected":"838869bdda93f25e6d50b3f50ae9577d9b19a586"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0.8.7"},{"last_affected":"0.9.5"}]}}],"versions":["v0.9.5","docker-rebuild-v0.9.5","v0.9.2","docker-rebuild-v0.9.2","v0.9.3","docker-rebuild-v0.9.3","v0.9.1","docker-rebuild-v0.9.1","v0.9.0","docker-rebuild-v0.9.0","v0.8.9","docker-rebuild-v0.8.9","v0.8.8","docker-rebuild-v0.8.8","v0.8.7","docker-rebuild-v0.8.7"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112363.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
