CVE-2026-0554
The NotificationX plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'regenerate' and 'reset' REST API endpoints in all versions up to, and including, 3.1.11.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
