The Hide Links plugin for WordPress is vulnerable to unauthorized shortcode execution due to do_shortcode being hooked through the comment_text filter in all versions up to and including 1.4.2. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes available on the target site.

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.
