No source in this snapshot names a fixed version.

Description

The Adwised Web Push Notification WordPress plugin through 2.5.7 does not perform any capability or nonce check before allowing an authenticated user to overwrite its site-wide configuration, and does not escape those configuration values before printing them inside an inline script block on every front-end page, allowing any authenticated user, such as a subscriber, to perform Stored Cross-Site Scripting attacks against every visitor, including administrators.
