- →The stored XSS payload is injected via the $url variable and rendered unsanitised in an HTML attribute within the Activity tab of the WP Cerber dashboard. Monitor HTTP requests to the plugin's activity-logging endpoint for payloads containing event-handler injections (e.g. onmouseover=) or quote-breaking sequences in URL parameters. ↗
- →The vulnerability is unauthenticated, meaning any unauthenticated HTTP request carrying a malicious URL value can plant the stored XSS payload. Detection rules should cover unauthenticated POST/GET requests to WP Cerber endpoints that include quote characters or JavaScript event handlers in URL-type fields. ↗
- ·Vulnerability is present in WP Cerber Security plugin versions before 8.9.6; ensure detections are scoped to environments running affected versions. ↗
