What the vulnerability does
01Description
The Reuse Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'reuse_builder_single_post_title' shortcode in all versions up to, and including, 1.7. This is due to insufficient input sanitization and output escaping on the 'style' attribute. 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.

An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other users, including site administrators. The vulnerability affects the entire site scope due to how the application processes and stores user input without proper sanitization.
