The Category and Taxonomy Meta Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the image meta field value in the 'wpaft_add_meta_textinput' function in versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with editor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The Category and Taxonomy Meta Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'new_meta_name' parameter in the 'wpaft_option_page' function in versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with administrator-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The Category and Taxonomy Meta Fields plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.0.0. This is due to missing or incorrect nonce validation on the 'wpaft_option_page' function. This makes it possible for unauthenticated attackers to add and delete taxonomy meta, granted they can trick a site administrator into performing an action such as clicking on a link.

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.
