Does this matter?

Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.

Description

The Responsive WordPress Slider WordPress plugin through 2.2.0 does not sanitise and escape some of the Slider options, allowing Cross-Site Scripting payloads to be set in them. Furthermore, as by default any authenticated user is allowed to create Sliders (https://wordpress.org/support/topic/slider-can-be-changed-from-any-user-even-subscriber/, such settings can be changed in the plugin's settings), this would allow user with a role as low as subscriber to perform Cross-Site Scripting attacks against logged in admins viewing the slider list and could lead to privilege escalation by creating a rogue admin account for example.
