Potential fix for https://github.com/ksel172/Meduza/security/code-scanning/4

To address the issue, the user-provided value (payloadId) must be properly validated before constructing the file path. Since payloadId is expected to correspond to a specific payload identifier, it should be checked against an allowlist or validated to ensure it does not contain path traversal sequences (e.g., .., /, \) or other disallowed characters.

The best fix involves:

  1. Using a validation function to ensure that payloadId is a valid single path component (e.g., alphanumeric characters and/or hyphens only).
  2. Rejecting requests with invalid payloadId by returning an HTTP 400 error.
  3. Constructing the file path using the validated payloadId.
