{"id":"CVE-2024-5986","state":"PUBLISHED","title":"Remote Arbitrary File Write with Arbitrary Data in h2oai/h2o-3","description":"A vulnerability in h2oai/h2o-3 version 3.46.0.1 allows remote attackers to write arbitrary data to any file on the server. This is achieved by exploiting the `/3/Parse` endpoint to inject attacker-controlled data as the header of an empty file, which is then exported using the `/3/Frames/framename/export` endpoint. The impact of this vulnerability includes the potential for remote code execution and complete access to the system running h2o-3, as attackers can overwrite critical files such as private SSH keys or script files.","publishedAt":"2026-02-02T10:36:24.550Z","updatedAt":"2026-02-02T13:13:23.762Z","severity":{"score":9.1,"label":"Critical","version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","source":"@huntr_ai"},"assigner":"@huntr_ai","products":["h2oai h2oai/h2o-3"],"affected":[{"vendor":"h2oai","product":"h2oai/h2o-3","versions":[{"version":"unspecified","status":"affected","lessThanOrEqual":"latest","versionType":"custom"}]}],"references":["https://huntr.com/bounties/64ff5319-6ac3-4447-87f7-b53495d4d5a3"],"weaknesses":["CWE-73"],"ingestedAt":"2026-10-29T20:08:12.933Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/5xxx/CVE-2024-5986.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-5986","state":"PUBLISHED","datePublished":"2026-02-02T10:36:24.550Z","dateUpdated":"2026-02-02T13:13:23.762Z","assignerShortName":"@huntr_ai","assignerOrgId":"c09c270a-b464-47c1-9133-acb35b22c19a","dateReserved":"2024-06-13T18:37:40.863Z"},"containers":{"cna":{"title":"Remote Arbitrary File Write with Arbitrary Data in h2oai/h2o-3","descriptions":[{"lang":"en","value":"A vulnerability in h2oai/h2o-3 version 3.46.0.1 allows remote attackers to write arbitrary data to any file on the server.
