Job Postings <= 2.8.2 - Authenticated (Contributor+) Arbitrary File Deletion

Description

The Job Postings plugin for WordPress is vulnerable to Arbitrary File Deletion due to insufficient file path validation in the [function_or_param] function in all versions up to, and including, 2.8.2. This makes it possible for authenticated attackers, with contributor-level access and above, 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).
