CVE-2024-7768

Denial of Service in h2oai/h2o-3

Published Mar 20, 2025 CVSS 3.0 · 7.5 High EPSS < 1% KEV · Not listed
Description
A vulnerability in the `/3/ImportFiles` endpoint of h2oai/h2o-3 version 3.46.1 allows an attacker to cause a denial of service. The endpoint takes a single GET parameter, `path`, which can be recursively set to reference itself. This leads the server to repeatedly call its own endpoint, eventually filling up the request queue and leaving the server unable to handle other requests.
