Get Post Content Shortcode <= 0.4 - Insecure Direct Object Reference to Authenticated (Contributor+) Sensitive Information Disclosure via post_content Shortcode

The Get Post Content Shortcode plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 0.4 via the 'post-content' shortcode due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the content of password-protected, private, draft, and pending posts.
