→Monitor for unsanitized script injection in the Popup Maker 'Cookie Time' field under Popup Settings > Triggers > Add New Cookie. The XSS payload is stored in the Cookie Time parameter, which normally holds a value like '1 month'. ↗
→Alert on authenticated POST requests to WordPress Popup Maker plugin endpoints where the Cookie Time field contains script tags or JavaScript event handlers rather than a time-duration value. ↗

·The vulnerability is exploitable even when the WordPress 'unfiltered_html' capability is disallowed, meaning standard hardening of that capability does NOT prevent this attack. ↗
·Exploitation requires authentication as a high-privilege user (e.g., admin), so this is an authenticated Stored XSS, not an unauthenticated one. ↗
