What the vulnerability does

01Description

The Wonka Slide plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `list_class` shortcode in all versions up to, and including, 1.3.3 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

02Summary

Wonka Slide versions 1.3.3 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 itself. Low-privileged users can exploit this without user interaction to compromise site integrity and access sensitive information.
