The plugin ACF Quick Edit Fields for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.2.2. This makes it possible for attackers without the edit_users capability to access metadata of other users, this includes contributor-level users and above.

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.
