{"id":"CVE-2026-109237","summary":"Crawl4AI 0.9.0 before 0.9.4 Untrusted Config Gate Bypass Leaks Environment Variables","details":"Crawl4AI from 0.9.0 before 0.9.4 contains an untrusted-config gate bypass that allows non-admin API clients to construct forbidden config objects by wrapping them in dict-type wrappers. Attackers can send a laundered LLMConfig with api_token set to an env reference via /config/dump to read SECRET_KEY and provider keys, enabling admin JWT forgery.","aliases":["GHSA-5w5p-vcv6-mm3f"],"modified":"2026-10-13T02:46:15.360118688Z","published":"2026-10-12T16:04:15Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109237.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-502"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/109xxx/CVE-2026-109237.json"},{"type":"ADVISORY","url":"https://github.com/unclecode/crawl4ai/security/advisories/GHSA-5w5p-vcv6-mm3f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-109237"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/crawl4ai-0.9.0-before-0.9.4-untrusted-config-gate-bypass-leaks-environment-variables"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/unclecode/crawl4ai","events":[{"introduced":"c66f3276fd355031c8632500911fe7041ad6fc14"},{"fixed":"133e1d92e37885dfccc03ea2e3687d06c98b7ceb"}],"database_specific":{"extracted_events":[{"introduced":"0.9.0"},{"fixed":"0.9.4"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.9.0","docker-rebuild-v0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-109237.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
