The vulnerability arises from the `exportModelDetails` function in `ModelsHandler.java`, where the user-controllable `mexport.dir` parameter is used to specify the file path for writing model details. This can lead to overwriting files at arbitrary locations on the host system.","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:L/A:H","score":8.2},"cwes":["CWE-73"],"references":["https://huntr.com/bounties/aebf69a5-b9b1-4d2f-a8ff-902c11a8c97a"],"products":["h2o:h2o"],"source":"nvd","synced_at":"2026-10-19T22:00:17.429720821+00:00"},"epss":{"cve":"CVE-2024-8616","score":0.00557,"percentile":0.46454,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-g48v-3p35-88jr","url":"https://osv.dev/vulnerability/GHSA-g48v-3p35-88jr","summary":"H2O Vulnerable to Arbitrary File Overwrite","modified":"2026-07-07T17:56:21.858937760Z","packages":[{"ecosystem":"PyPI","name":"h2o","purl":"pkg:pypi/h2o","ranges":[">=3.10.4.1 <=3.46.0"],"fixed":[]},{"ecosystem":"Maven","name":"ai.h2o:h2o-core","purl":"pkg:maven/ai.h2o/h2o-core","ranges":[">=3.10.4.1 <=3.46.0"],"fixed":[]}]},{"id":"PYSEC-2026-1441","url":"https://osv.dev/vulnerability/PYSEC-2026-1441","summary":"H2O Vulnerable to Arbitrary File Overwrite","modified":"2026-07-07T17:46:12.517317926Z","packages":[{"ecosystem":"PyPI","name":"h2o","purl":"pkg:pypi/h2o","ranges":[">=3.10.4.1 <=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).
