Remote attackers can exploit insufficient path validation and symlink following to achieve arbitrary file write and potential code execution on systems where the runtime user has write access to executable or cron locations.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-22"],"references":["https://github.com/unclecode/crawl4ai/security/advisories/GHSA-7cx2-g3h9-382p","https://www.vulncheck.com/advisories/crawl4ai-arbitrary-file-write-via-output-path-symlink-and-toctou"],"products":["kidocode:crawl4ai"],"source":"nvd","synced_at":"2026-10-19T22:39:28.638635428+00:00"},"epss":{"cve":"CVE-2026-56258","score":0.00912,"percentile":0.60049,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-7cx2-g3h9-382p","url":"https://osv.dev/vulnerability/GHSA-7cx2-g3h9-382p","summary":"Crawl4AI: Arbitrary file write (symlink/TOCTOU) plus log and webhook-header injection in Docker server","modified":"2026-07-21T15:15:49.444148882Z","packages":[{"ecosystem":"PyPI","name":"crawl4ai","purl":"pkg:pypi/crawl4ai","ranges":["<0.8.8"],"fixed":["0.8.8"]}]},{"id":"PYSEC-2026-228","url":"https://osv.dev/vulnerability/PYSEC-2026-228","summary":"","modified":"2026-06-26T12:45:05.457992283Z","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).
