The endpoint takes a single GET parameter, `path`, which can be recursively set to reference itself. This leads the server to repeatedly call its own endpoint, eventually filling up the request queue and leaving the server unable to handle other requests.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://huntr.com/bounties/3fe640df-bef4-4072-8890-0d12bc2818f6"],"products":["h2o:h2o"],"source":"nvd","synced_at":"2026-10-19T22:00:17.429720821+00:00"},"epss":{"cve":"CVE-2024-7768","score":0.00788,"percentile":0.5619,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p2vc-m5fv-9w9m","url":"https://osv.dev/vulnerability/GHSA-p2vc-m5fv-9w9m","summary":"H2O Vulnerable to Denial of Service (DoS) via `/3/ImportFiles` Endpoint","modified":"2026-09-10T03:49:48.504834427Z","packages":[{"ecosystem":"PyPI","name":"h2o","purl":"pkg:pypi/h2o","ranges":["<=3.46.1"],"fixed":[]},{"ecosystem":"Maven","name":"ai.h2o:h2o-core","purl":"pkg:maven/ai.h2o/h2o-core","ranges":["<=3.46.1"],"fixed":[]}]},{"id":"PYSEC-2026-1443","url":"https://osv.dev/vulnerability/PYSEC-2026-1443","summary":"H2O Vulnerable to Denial of Service (DoS) via `/3/ImportFiles` Endpoint","modified":"2026-07-07T17:46:12.496094825Z","packages":[{"ecosystem":"PyPI","name":"h2o","purl":"pkg:pypi/h2o","ranges":["<=3.46.1"],"fixed":[]}]}],"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).
