WordPress GDPR & CCPA plugin before 1.9.27 contains a cross-site scripting vulnerability. The check_privacy_settings AJAX action, available to both unauthenticated and authenticated users, responds with JSON data without an "application/json" content-type, and JavaScript code may be executed on a victim's browser.
2023-09-06 11:59:08 +00:00
remediation : Version 1.9.26 has added a CSRF check. This vulnerability is only exploitable against unauthenticated users.
