## Technical details

The plugin lacks authorization and CSRF protections on its settings update functionality and fails to properly escape output of stored settings, enabling unauthenticated stored XSS (CWE-79). An attacker sends a crafted request to modify settings with injected JavaScript payloads, which persist in the database and execute in the browsers of admins and visitors. No authenticated access or user interaction with the attacker's content is required.
