The provided vulnerability information describes malicious behavior (form field enumeration and data exfiltration) but does not include specific code snippets, commit diffs, or file paths that would allow identification of exact function names or their locations. The advisory references third-party sources (GitHub/Snyk) that might contain more details, but these are not accessible in the provided context. Without concrete evidence of the malicious code structure or implementation details, we cannot confidently map the described behavior to specific functions in the codebase.
