Miggo AIRoot Cause Analysis

The vulnerability stems from insecure XML parsing in the FindBugs report processing. The advisory specifically mentions disabling external entity resolution as the fix. In Java XML processing, this typically involves DocumentBuilderFactory configuration. The FindBugsParser class would contain the XML parsing logic for processing analysis reports, and its parse method would be responsible for XML handling. While exact code isn't available, the pattern matches standard XXE vulnerabilities where XML parsers aren't properly secured with features like FEATURE_SECURE_PROCESSING or explicit disabling of DTDs.
