Technical details
The vulnerability is a stored cross-site scripting (XSS) flaw caused by insufficient input sanitization and output escaping in WP Activity Log versions up to 5.6.1. An unauthenticated attacker can inject arbitrary JavaScript that persists in the plugin's data store and executes in users' browsers when they access injected pages. The stored nature of this XSS makes it more dangerous than reflected variants, as it affects all users who visit the compromised pages.
