What the vulnerability does
The Radius Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘subHeadingTagName’ parameter in all versions up to, and including, 2.2.1 due to insufficient input sanitization and output escaping. 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.

The Radius Blocks plugin for WordPress contains a stored cross-site scripting (XSS) vulnerability in versions up to 2.2.1. An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other site visitors, potentially compromising their accounts or stealing sensitive data. The vulnerability affects the site's scope, meaning the injected code can impact multiple users and components.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they view affected pages.
Potential impact on your site
