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 Advanced Woo Search plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the search parameter in all versions up to, and including, 2.96 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This only affects sites when the Dynamic Content for Elementor plugin is also installed.

The Advanced Woo Search plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 2.77 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, 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 Advanced Woo Search plugin version through 1.99 for Wordpress suffers from a sensitive information disclosure vulnerability in every ajax search request via the sql field to includes/class-aws-search.php.
