Name of the Vulnerable Software and Affected Versions h2oai/h2o-3 versions prior to 3.46.0.8 h2oai/h2o-3 version 3.47.0.99999

Description A vulnerability in the h2oai/h2o-3 repository allows attackers to exploit deserialization of untrusted data, potentially leading to arbitrary code execution and reading of system files. This issue arises from the ability to bypass regular expression filters intended to prevent malicious parameter injection in JDBC connections.
