CVE-2021-24544 Information

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.
