CVSS Score
-The vulnerability stems from insecure XML parsing in the XSL transformation process. The patch explicitly adds 'factory.setFeature(XMLConstants.FEATURE_SECURE_PROCESSING, true)' to the TransformerFactory initialization in InputHandler.java. The absence of this security feature in versions ≤2.9 leaves the XML parser vulnerable to XXE attacks by not restricting external entity references. The transformTo method is directly modified in the fix, confirming it as the vulnerable code path.
