The GDPR Cookie Compliance plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the gdprcookiecomplianceresetsettings AJAX action in versions up to, and including, 4.0.2. This makes it possible for authenticated attackers to reset all of the settings.

The GDPR Cookie Compliance – Cookie Banner, Cookie Consent, Cookie Notice – CCPA, DSGVO, RGPD plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.15.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfilteredhtml has been disabled.
