The vulnerability explicitly cites the RemoveXSS function, and commit diffs (aba23d6/ce47d8d) show the flawed single-pass regex replacement was replaced with a while-loop to handle nested encodings. The backend-related XSS is mentioned in advisories but lacks specific function/file references in the provided data, making it impossible to identify concrete functions with high confidence.
