- GHSA-gqrq-j6pm-98c2External Control of File Name or Path in h2oai/h2o-32023-12-14ghsa · osvUS
Remote unauthenticated attackers can overwrite arbitrary server files with attacker-controllable data. The data that the attacker can control is not entirely arbitrary. h2o writes a CSV/XLS/etc file to disk, so the attacker data is wrapped in quotations and starts with "C1", if they're exporting as CSV.
