{"schema":"threatline.record/2","record":{"id":"CVE-2024-5986","aliases":["GHSA-wj3h-wx8g-x699","PYSEC-2026-353"],"summary":"H2O has an External Control of File Name or Path vulnerability","details":"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.","categories":["Libraries & packages"],"product":"ai.h2o:h2o-core","vendor":"h2oai","ecosystem":"maven","affected_ranges":[{"source":"GitHub Advisory
