WP Easy Post Types <= 1.4.4 - Authenticated (Subscriber+) Missing Authorization via Multiple Functions

The WP Easy Post Types plugin for WordPress is vulnerable to unauthorized access, modification, and loss of data due to a missing capability check on multiple functions in all versions up to, and including, 1.4.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to add, modify, or delete plugin options and posts.

WP Easy Post Types <= 1.4.4 - Authenticated (Subscriber+) PHP Object Injection

The WP Easy Post Types plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.4.4 via deserialization of untrusted input from the 'text' parameter in the 'ajax_import_content' function. This allows authenticated attackers, with subscriber-level permissions and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Cross-site scripting (XSS) vulnerability in classes/custom-image/media.php in the WP Easy Post Types plugin before 1.4.4 for WordPress allows remote attackers to inject arbitrary web script or HTML via the ref parameter.
