CVE-2024-10549 Information

Description

A vulnerability in the /3/Parse endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack. The endpoint uses a user-specified string to construct a regular expression which is then applied to another user-specified string. By sending multiple simultaneous requests an attacker can exhaust all available threads leading to a complete denial of service.
