Name of the Vulnerable Software and Affected Versions h2oai/h2o-3 version 3.46.0

Description A denial of service issue exists due to a vulnerability in the typeahead endpoint. 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.

Recommendations For h2oai/h2o-3 version 3.46.0, consider implementing a timeout for the HEAD request in the typeahead endpoint to prevent the application from becoming unresponsive. As a temporary workaround, restrict access to the typeahead endpoint to minimize the risk of exploitation.
