Miggo AIRoot Cause Analysis

The patches explicitly modify XML parser creation points to disable XXE features. The vulnerable versions lacked these security settings in three key locations: 1) SAXParser creation in Util.java, 2) DocumentBuilder creation in XMLUtil.java (core XML handling), and 3) DOM parsing in Project2Case.java (project file loading). All three would appear in stack traces when processing malicious XML input. Medium confidence for Project2Case.toDOMTree as it's test code, but the identical patch pattern suggests it was used in production flows.
