Content Mask 1.7.1 - 1.8.5.5 - Contributor+ Stored XSS via Post Scripts and Styles

Description

The plugin does not properly sanitise and escape content submitted with a post before outputting it in the pages it generates, allowing users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks against any user viewing or previewing the affected page.
The plugin's option to restrict its use by role does not prevent this.
