🛡️ Sentinel: [HIGH] Fix path traversal in SetPortrait - #215
Conversation
🚨 Severity: HIGH
💡 Vulnerability: A path traversal vulnerability was present in `CustomEmployeeManager.SetPortrait` where unvalidated `employeeId` strings from external mods could be used in file path construction.
🎯 Impact: Allowed malicious mods to access arbitrary files on the user's system by crafting paths using `../` in the `employeeId` parameter when attempting to load portraits.
🔧 Fix: Added independent path traversal validation `IndexOfAny(Path.GetInvalidFileNameChars()) < 0 && !employeeId.Contains("..")` for the `employeeId` before constructing the file path, gracefully falling back to a default solid teal color if validation fails.
✅ Verification: Run `dotnet test` to verify the codebase functions as expected and verify that the `SetPortrait` method safely rejects identifiers containing path navigation characters.
