Official description
The MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar plugin for WordPress is vulnerable to unauthorized arbitrary file deletion due to a missing capability check on the removeTempFiles() function and insufficient path validation on the 'file' parameter in all versions up to, and including, 5.7.0.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files which can make remote code execution possible when wp-config.php is deleted.

The underlying weakness: Missing Authorization
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
How developers prevent this class of flaw
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
- Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using authorization frameworks such as the JAAS Authorization Framework and the OWASP ESAPI Access Control feature.
