{"id":"CVE-2026-57573","aliases":["GHSA-wm69-2pc3-rmmf","PYSEC-2026-2140"],"url":"https://o3.security/vulnerability/CVE-2026-57573","summary":"Crawl4AI unauthenticated SSRF in Docker streaming crawl endpoint","details":"Crawl4AI is an open-source LLM-friendly web crawler and scraper. Prior to 0.9.0, the Docker API server applied its SSRF destination check on the non-streaming /crawl path but not on the streaming path. handle_stream_crawl_request passed seed URLs straight to the crawler with no destination validation, allowing a remote unauthenticated client to call POST /crawl/stream or POST /crawl with crawler_config.stream=true with a URL pointing at an internal, private, or link-local address; the server fetched it and streamed the response body back. This issue is fixed in version 0.9.0.","published":"2026-07-06T20:11:15.691Z","modified":"2026-08-12T03:51:32.406277027Z","cvss":{"score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"},"epss":{"score":0.00445,"percentile":0.37579,"asOf":"2026-09-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"crawl4ai","fixedVersion":"0.9.0"}],"fix":{"url":"https://github.com/unclecode/crawl4ai/commit/60886d1a0c52682e4c83a7cef9dfac417fff6bd2","label":"unclecode/crawl4ai@60886d1"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57573.json"},{"type":"ADVISORY","url":"https://github.com/unclecode/crawl4ai/security/advisories/GHSA-wm69-2pc3-rmmf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57573"},{"type":"FIX","url":"https://github.com/unclecode/crawl4ai/commit/60886d1a0c52682e4c83a7cef9dfac417fff6bd2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:32.406277027Z"}}
