Root Cause Analysis
The vulnerability stems from improper handling of XML nodes containing comments during text extraction. While no direct patch diffs are provided, the CVE description and Duo's analysis indicate the core issue exists in functions processing SAML assertion content. The library's XML parsing logic for critical elements like NameID would be the primary location for this vulnerability, specifically where text content is extracted using methods vulnerable to comment truncation. These functions would appear in runtime profiles during SAML response processing and signature validation.
