Miggo AIRoot Cause Analysis

The vulnerability (CVE-2018-1000865) stems from improper handling of finalize() methods in the Groovy sandbox. The commit diff shows added tests verifying that finalizers are blocked, and the groovy-sandbox dependency was updated to 1.20 which includes the fix. The SandboxTransformer is responsible for applying security transformations to Groovy code, and its failure to restrict finalize() methods (a special JVM lifecycle method) created the sandbox bypass. The test cases explicitly check for SecurityException when defining finalize() methods, confirming this was the attack vector.
