Root Cause Analysis

The provided vulnerability information does not include specific code references, commit diffs, or technical details about the SignalR implementation flaw. While the advisory clearly states the vulnerability exists in ASP.NET applications using SignalR, Microsoft's documentation and CVE description do not disclose exact function names or file paths. Identification of specific vulnerable functions would require analysis of the patched code changes in ASP.NET Core's SignalR component, which is not included in the provided materials. The 'Current Vulnerable Functions' fields in all listed packages are empty in the input data, further indicating this information is not publicly disclosed.
