CVE-2024-56220Network attack vector

Unauthenticated Administrator privilege escalation

Published Dec 31, 2024 · Updated May 11, 2026

Incorrect privilege assignment in SSL Wireless SMS Notification 3.6.0 and earlier allows remote attackers to gain Administrator access. Published advisories do not identify the affected endpoint, function, or operation on untrusted input, so the concrete mechanism remains undisclosed. Exploitation requires network access to a WordPress site with the plugin active but requires neither authentication nor user interaction, and Administrator access permits full site control.
