Vulnerability from github – Published: 2026-07-10 09:31 – Updated: 2026-07-10 09:31

Details

The GDPR Cookie Consent plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check and missing nonce verification on the gdpr_cookie_consent_ajax_save_schedule_scan() function (the wp_ajax_gcc_save_schedule_scan AJAX action) in versions up to, and including, 4.3.6. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify the plugin's cookie scan schedule configuration stored in the gdpr_scan_schedule_data option, which is an administrative function intended to be limited to users with the manage_options capability.

Severity

4.3 (Medium)
