Miggo AIRoot Cause Analysis

The vulnerability stemmed from two key issues: 1) The classloader creation (Util.createClassLoader) accepted user-controlled paths, allowing loading of arbitrary classes. 2) Driver classname configuration (via PropertiesAssembler) permitted execution of arbitrary static initializers. Commit 1817af0 shows classloader refactoring to prevent workspace-relative paths, while 382a1ea removed driver classname customization - both indicating these were the attack vectors. The high severity CVE-2018-1000146 directly maps to these insecure class loading mechanisms.
