## Overview

The Responsive Progress Bar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's rprogress shortcode in versions less than, or equal to, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
