Attackers can exploit the unauthenticated /md, /llm, and /llm/job endpoints by supplying a malicious base_url parameter and setting api_token to env:VARIABLE_NAME to exfiltrate provider API keys and server secrets including JWT SECRET_KEY for authentication bypass.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","score":8.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","score":8.2},"cwes":["CWE-200"],"references":["https://github.com/unclecode/crawl4ai/security/advisories/GHSA-f989-c77f-r2cq","https://www.vulncheck.com/advisories/crawl4ai-llm-credential-exfiltration-via-base-url-and-environment-variable-resolution"],"products":["kidocode:crawl4ai"],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-56259","score":0.00433,"percentile":0.37645,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-f989-c77f-r2cq","url":"https://osv.dev/vulnerability/GHSA-f989-c77f-r2cq","summary":"Crawl4AI: LLM credential exfiltration in Docker server via request base_url and env: token resolution","modified":"2026-07-15T20:11:30.371628850Z","packages":[{"ecosystem":"PyPI","name":"crawl4ai","purl":"pkg:pypi/crawl4ai","ranges":["<0.8.8"],"fixed":["0.8.8"]}]},{"id":"PYSEC-2026-3448","url":"https://osv.dev/vulnerability/PYSEC-2026-3448","summary":"","modified":"2026-07-15T20:00:06.248966718Z","packages":[{"ecosystem":"PyPI","name":"crawl4ai","purl":"pkg:pypi/crawl4ai","ranges":["<0.8.8"],"fixed":["0.8.8"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
