Miggo AIRoot Cause Analysis

The vulnerability stems from StaxParserUtil's attribute handling where system property substitution occurred. The commit removes this behavior specifically in getAttributeValue(), which processes XML attributes during SAML parsing. This function would appear in stack traces when processing malicious SAML requests containing ${sys:...} patterns, as it directly handled the vulnerable substitution logic prior to patching.
