What the vulnerability does
The Canto Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fx' shortcode attribute in all versions up to, and including, 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.

The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component to affect other parts of the application or other users. Low-level authentication is required to exploit this issue.
What an attacker can do
