The GetFileName method could be vulnerable to path traversal attacks if a malicious file hash contained path components like "../" or directory separators. This fix adds: - Explicit removal of path separators (/ and \) - Explicit removal of parent directory references (..) - Final validation that the resolved path is within the expected directory - Null/empty check for file hash input Co-Authored-By: Claude Opus 4.5 <[email protected]>
