Multiple plugins for WordPress are vulnerable to Stored Cross-Site Scripting via the plugin's bundled FancyBox JavaScript library (versions 1.3.4 to 3.5.7) in various versions due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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 WP Mobile Menu plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the save_menu_item_icon function in all versions up to, and including, 2.8.4.4. This makes it possible for unauthenticated attackers to add the '_mobmenu_icon' post meta to arbitrary posts with an arbitrary (but sanitized) value. NOTE: Version 2.8.4.4 contains a partial fix for this vulnerability.
