The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

The Delete All Comments plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the via the delete-all-comments.php file in versions up to, and including, 2.0. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.

The Delete All Comments Easily WordPress plugin through 1.3 is lacking Cross-Site Request Forgery (CSRF) checks, which could result in an unauthenticated attacker making a logged in admin delete all comments from the blog.
