The endpoint performs a `HEAD` request to verify the existence of a specified resource without setting a timeout. An attacker can exploit this by sending multiple requests to an attacker-controlled server that hangs, causing the application to block and become unresponsive to other requests.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-1088"],"references":["https://huntr.com/bounties/a04190d9-4acb-449a-9a7f-f1bf6be1ed23","https://huntr.com/bounties/a04190d9-4acb-449a-9a7f-f1bf6be1ed23"],"products":["h2o:h2o"],"source":"nvd","synced_at":"2026-10-19T22:00:17.429720821+00:00"},"epss":{"cve":"CVE-2024-8062","score":0.00482,"percentile":0.41609,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-5c8j-g96x-cj78","url":"https://osv.dev/vulnerability/GHSA-5c8j-g96x-cj78","summary":"H2O Vulnerable to Denial of Service (DoS) via `HEAD` Request","modified":"2026-07-07T17:57:09.968843693Z","packages":[{"ecosystem":"PyPI","name":"h2o","purl":"pkg:pypi/h2o","ranges":[">=3.2.0.1 <=3.46.0"],"fixed":[]},{"ecosystem":"Maven","name":"ai.h2o:h2o-core","purl":"pkg:maven/ai.h2o/h2o-core","ranges":[">=3.2.0.1 <=3.46.0"],"fixed":[]}]},{"id":"PYSEC-2026-1438","url":"https://osv.dev/vulnerability/PYSEC-2026-1438","summary":"H2O Vulnerable to Denial of Service (DoS) via `HEAD` Request","modified":"2026-07-07T17:47:39.962990287Z","packages":[{"ecosystem":"PyPI","name":"h2o","purl":"pkg:pypi/h2o","ranges":[">=3.2.0.1 <=3.46.0"],"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).
