Super Progressive Web Apps
Monthly
Stored XSS in the Super Progressive Web Apps WordPress plugin (all versions through 2.2.43) enables authenticated WordPress administrators to persist arbitrary JavaScript payloads via the offline snackbar message setting, which executes in the browsers of site visitors when their browser transitions offline. The offline message is stored without sanitization, serialized into the page via wp_localize_script(), and rendered through innerHTML in the PWA snackbar component - a classic stored-to-DOM XSS chain crossing the administrator-to-visitor security boundary. No public exploit code or CISA KEV listing exists at time of analysis; the high privilege requirement substantially constrains real-world attack surface.
