Is this vulnerability remotely exploitable by anonymous users?

No. Exploitation requires an authenticated account with administrative or Change Settings privileges. However, if an attacker compromises such an account through other means (e.g., credential theft), they can leverage this vulnerability for full application compromise.

What level of access is needed to take advantage of this issue?

The attacker must be able to log into the Chyrp Lite administration console with sufficient privileges to modify the uploads path configuration. There is no requirement for shell or file-level access to the server; the exploit can be carried out entirely through the web interface once the appropriate permissions are obtained.

What is the safest general fix pattern for affected code?

The safest approach is to remove or tightly restrict any configuration that lets users choose arbitrary filesystem paths, and instead enforce a fixed, application-controlled uploads directory. Any remaining path configuration should be normalized, validated against a whitelist of allowed directories, and rejected if it attempts to traverse outside the permitted area.
