- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- wplegalpages Cookie Banner for GDPR / CCPA – WPLP Cookie Consent: through 4.3.6

## Description

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.
