What the vulnerability does
The Optio Dentistry plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'optio-lightbox' shortcode in all versions up to, and including, 2.2 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.
Explanation of Vulnerability in Simple Terms
Optio Dentistry versions 2.2 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component to affect other users or systems. Low-privilege accounts can exploit this without user interaction.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other users' sessions, data, or site behavior.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
