The /execute_js, /screenshot, /pdf, and /html endpoints accept file:// URLs, allowing attackers to read arbitrary files from the server filesystem.\n\nAttack Vector:\n```json\nPOST /execute_js\n{\n    \"url\": \"file:///etc/passwd\",\n    \"scripts\": [\"document.body.innerText\"]\n}\n```\nImpact\n\nAn unauthenticated attacker can:\n- Read sensitive files (/etc/passwd, /etc/shadow, application configs)\n- Access environment variables via /proc/self/environ\n- Discover internal application structure\n- Potentially read credentials and API keys\n\nWorkarounds\n\n1. Disable the Docker API\n2. Add authentication to the API\n3. Use network-level filtering","published":"2026-02-12T15:33:27.454Z","modified":"2026-08-12T03:51:42.113663965Z","cvss":null,"epss":{"score":0.00609,"percentile":0.45842,"asOf":"2026-08-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"crawl4ai","fixedVersion":"0.8.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26217.json"},{"type":"ADVISORY","url":"https://github.com/unclecode/crawl4ai/blob/main/docs/blog/release-v0.8.0.md"},{"type":"ADVISORY","url":"https://github.com/unclecode/crawl4ai/security/advisories/GHSA-vx9w-5cx4-9796"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26217"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/crawl4ai-docker-api-local-file-inclusion-via-file-url-handling"},{"type":"PACKAGE","url":"https://github.com/unclecode/crawl4ai"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/crawl4ai/PYSEC-2026-34.yaml"},{"type":"WEB","url":"https://github.com/unclecode/crawl4ai/blob/release/v0.8.0/docs/blog/release-v0.8.0.md"},{"type":"WEB","url":"https://github.com/unclecode/crawl4ai/blob/release/v0.8.0/docs/migration/v0.8.0-upgrade-guide.md"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:42.113663965Z"}}
