The Slider Hero with Video Background, Animation WordPress plugin before 9.1.3 does not have authorisation and nonce checks on two of its request handlers, and does not escape a stored setting before outputting it, allowing unauthenticated users to store malicious JavaScript which will be executed in the context of an administrator viewing the Slider Hero with Video Background, Animation WordPress plugin before 9.1.3's admin area, as well as any visitor of a page embedding a slider.
