Description
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.

Executive Summary

The vulnerability in the Responsive Progress Bar WordPress plugin (version 1.0 and below) is a Stored Cross-Site Scripting (XSS) issue. It occurs because the plugin does not properly sanitize or escape user-supplied attributes in its rprogress shortcode. This allows authenticated users with contributor-level access or higher to inject malicious scripts that execute whenever any user views the affected page.

Impact Analysis

This vulnerability can allow attackers with contributor-level access to inject malicious JavaScript into pages, which will execute in the browsers of users who visit those pages. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed in the context of the affected website.

Mitigation Strategies

To mitigate this vulnerability, immediately remove or deactivate the Responsive Progress Bar plugin if it is installed, especially if it is version 1.0 or earlier. Since the plugin was closed and removed from availability as of October 17, 2025, pending a full security review, do not reinstall it until a secure version is released. Additionally, restrict contributor-level access and above to trusted users only to reduce risk of exploitation. [2]
