The provided information does not include specific code snippets, commit diffs, or patch details that would allow identification of exact vulnerable functions. While the vulnerability (CWE-74) suggests improper neutralization of user input used in HTTP headers, the lack of technical implementation details (e.g., class/method names, file paths, or code examples) makes it impossible to pinpoint specific functions with high confidence. HTTP header injection typically involves unsafe concatenation of user-controlled data into headers (e.g., via setHeader() or similar methods), but without concrete evidence from the codebase, no functions can be definitively identified.
