The Cookie Notice Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 1.3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, 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 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 Cookie Notice & Compliance for GDPR / CCPA plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'cookie_notice_options[refuse_code_head]' parameter in versions up to, and including, 2.4.17.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrative privileges and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the injected /wp-admin/admin.php?page=cookie-notice page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
