Custom Twitter Feeds < 2.3.0 - Cross-Site Request Forgery to Cache Reset via ctf_clear_cache_admin Function

Description

The Custom Twitter Feeds – A Tweets Widget or X Feed Widget plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.2.5. This is due to missing or incorrect nonce validation on the ctf_clear_cache_admin() function. This makes it possible for unauthenticated attackers to reset the plugin's cache via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
