Root Cause Analysis

The vulnerability stemmed from the build process configuration in pom.xml. The properties-maven-plugin's write-project-properties goal was used without filtering, automatically including all system properties (including sensitive GPG credentials) in designer.properties. This is evidenced by:

The diff showing gpg.passphrase removal from designer.properties
Commit 1548f5f replacing properties-maven-plugin with a more controlled properties writer
The CWE-540 classification indicating sensitive info in source code/build artifacts
The fix involved explicitly defining allowed properties rather than including all system properties
