🚨 Severity: MEDIUM
💡 Vulnerability:
SetPortraitinCustomEmployeeManagerconstructed file paths dynamically without its own validation, relying on caller validation. This created a path traversal vulnerability (CWE-22) via direct calls.🎯 Impact: An attacker could bypass registration validation and read arbitrary images from the filesystem by directly calling the method or using deserialization bypasses.
🔧 Fix: Wrapped the
Path.Combineand file loading logic in an input validation block checking for directory traversal characters (..) and invalid filename characters. The method will securely fallback to the default portrait color if invalid characters are detected.✅ Verification: The codebase compiles correctly and all unit tests continue to pass.
