The Apus Framework plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the 'import_page_options' function in all versions up to, and including, 2.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.

The WP Job Board Pro plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.2.76. This is due to the plugin allowing a user to supply the 'role' field when registering. This makes it possible for unauthenticated attackers to register as an administrator on vulnerable sites.

The WP Private Message WordPress plugin (bundled with the Superio theme as a required plugin) before 1.0.6 does not ensure that private messages to be accessed belong to the user making the requests. This allowing any authenticated users to access private messages belonging to other users by tampering the ID.

The Superio WordPress theme does not sanitise and escape some parameters, which could allow users with a role as low as a subscriber to perform Cross-Site Scripting attacks.

There are unauthenticated reflected Cross-Site Scripting (XSS) vulnerabilities in CareerUp Careerup WordPress theme before 2.3.1, via the filter parameters.
