GHSA-5C8J-G96X-CJ78
Vulnerability from github – Published: 2025-03-20 12:32 – Updated: 2025-03-20 20:29A vulnerability in the typeahead endpoint of h2oai/h2o-3 version 3.46.0 allows for a denial of service. The endpoint performs a HEAD request to verify the existence of a specified resource without setting a timeout. An attacker can exploit this by sending multiple requests to an attacker-controlled server that hangs, causing the application to block and become unresponsive to other requests.
