This vulnerability enables the possibility of invoking static Java classes from the Java Development Kit (JDK), allowing attackers to execute arbitrary code with the same permissions as the currently running Java process. Such exploitation can lead to severe security breaches, including unauthorized access and data compromise. Organizations using Apache Unomi should promptly review their configurations and apply necessary mitigations to safeguard against this threat.
