Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection in the executeSql process. An attacker can execute arbitrary code with the privileges of the server process by injecting malicious Java code into a column name, which is then compiled and executed by the unsandboxed Janino compiler. This is only exploitable if the attacker has the ControlArchiving system privilege.
