Description
The Super Progressive Web Apps plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Caching Strategies add-on's manual pre-caching URLs setting in all versions up to, and including, 2.2.48.1, due to insufficient input sanitization and output escaping. The URLs were saved without sanitization and placed directly inside single-quoted JavaScript strings in the generated service worker, so a quote character ends the string. This makes it possible for authenticated attackers with administrator-level access to inject arbitrary JavaScript into the site's service worker, which runs in the browsers of site visitors. This only affects multi-site installations and installations where unfiltered_html has been disabled.
