Root Cause Analysis
The vulnerability (CWE-776) stems from Nokogiri's failure to apply limits on XML entity expansion, leading to DoS via recursive entity references. However, the provided data lacks specific code references, commit diffs, or patch details. While the issue likely resides in functions configuring libxml2 parser options (e.g., setting entity expansion limits), the exact function names and file paths cannot be confidently identified without examining the patched code changes. Thus, no functions are listed with high confidence.
