Master Slider < 3.7.1 - Authenticated Stored Cross-Site Scripting (XSS)

Description

The plugin did not properly sanitise the slider name when creating or editing a slider, leading to an Authenticated (editor+) Stored Cross-Site Scripting issue which will be triggered in the Slider table (/wp-admin/admin.php?page=master-slider).

Edit (WPScanTeam):
- The original report was from 2018, however the issue was never remediated.
- Multiple attempts were made to contact the vendor, but no response was received
- April 28th, 2021, v3.7.1 released, fixing the issue
