Miggo AIRoot Cause Analysis

The commit diff shows added tests blocking 'x = Jenkins.getInstance()' in constructor parameters when calling super(), and the patch upgraded groovy-sandbox to handle these expressions. The vulnerability specifically involved improper handling of default parameter initializers in constructors with super calls, which would execute outside sandbox constraints. The test case demonstrates this bypass vector, and the CWE-94 classification confirms it's a code injection via uncontrolled code generation.
