Summary

The Adwised Web Push Notification WordPress plugin through 2.5.7 lacks authorisation checks on several state-changing operations, and its secret comparison can be bypassed where the secret key was never set. An unauthenticated attacker can store arbitrary JavaScript that runs in the browser of every site visitor (CWE-79). The CVSS 3.1 base score is 8.8 (HIGH), the vendor is unknown, and no fixed version is listed. CISA has not added it to KEV; its SSVC assessment marks it automatable with total technical impact and exploitation as none, and a public exploit link appears in the references.
