Technical details
An arbitrary file deletion vulnerability exists in BookCars <= v8.3 due to improper input validation in the /api/delete-temp-license/{file} endpoint. The application uses path.join() to concatenate a user-provided filename with a temporary directory path without sanitizing directory traversal sequences (e.g., '../'). An unauthenticated remote attacker can exploit this by sending a POST request containing URL-encoded traversal characters to delete any file the application process has permissions to access. The vulnerability is located in the deleteTempLicense controller within /backend/src/controllers/userController.ts. No official patch is confirmed, but mitigations include implementing path canonicalization and validating that the resolved path remains within the intended directory.
