Read More & Accordion <= 3.4.2 - Missing Authorization to Authenticated (Subscriber+) Arbitrary 'Read More' Post Deletion

The Read More & Accordion plugin for WordPress is vulnerable to unauthorized modification and loss of data due to a missing capability check on the expmDeleteData() function in all versions up to, and including, 3.4.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary 'read more' posts.
