WPLMS Learning Management System for WordPress < 4.963 - Unauthenticated Arbitrary File Read and Deletion

Description

The theme is vulnerable to arbitrary file read and deletion due to insufficient file path validation and permissions checks in the readfile and unlink functions. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The theme is vulnerable even when it is not activated.
