CVE-2026-6440

What is known

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.

Business impact

Successful exploitation of CVE-2026-6440, a medium vulnerability (CVSS 4.3) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
