What the vulnerability does
The OMIGO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `omigo_donate_button` shortcode in all versions up to, and including, 3.3 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
OMIGO versions 3.3 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts affecting other users across the application. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. Low-privileged accounts can exploit this without user interaction.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect the application's functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other users' sessions and data integrity across the application.
Conditions required to exploit
Attacker must have a low-privileged account; no user interaction required from victims.
