Stored cross-site scripting in Beds24 Online Booking 2.0.25 and earlier allows remote authenticated users to execute script through saved settings. The plugin renders stored setting values without output escaping; public material does not identify the specific field or function. Administrator-level privileges are required to store the value, and another page view supplies the required user interaction.
