Affected packages

• PyPI h2o: >= 3.30.0.7, <= 3.46.0.1 (no fix yet) • Maven ai.h2o:h2o-core: >= 3.30.0.7, <= 3.46.0.1 (no fix yet)

Description

A vulnerability in the `/3/ParseSetup` endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack. The endpoint applies a user-specified regular expression to a user-controllable string. This can be exploited by an attacker to cause inefficient regular expression complexity, leading to the exhaustion of server resources and making the server unresponsive.
