CVE-2026-87762: Unknown Adwised Web Push Notification

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

The Adwised Web Push Notification WordPress plugin through 2.5.7 does not have authorisation checks on several state-changing operations, and the secret comparison it uses instead can be bypassed on installations where the secret key has never been set, allowing unauthenticated users to store arbitrary JavaScript that is executed in the browser of every site visitor.

Affected products

• Unknown Adwised Web Push Notification: up to and including 2.5.7
