The GoodMeet – Google Meet Integration for Webinar, Meeting & Video Conference plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.1.8. This is due to a missing nonce verification in the reset_credential() function, which handles the wp_ajax_goodmeet_reset_google_meet_credential AJAX action. While the function does verify the user's capability (manage_options), it does not validate a nonce, making it susceptible to CSRF attacks. This makes it possible for unauthenticated attackers to trick a site administrator into clicking a malicious link that will reset (delete) the plugin's stored Google Meet API credentials (goodmeet_google_credentials) and OAuth tokens (goodmeet_google_token), effectively disabling the Google Meet integration on the site.
