What the vulnerability does

01Description

The Simple Tableau Viz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tableau' shortcode in all versions up to, and including, 2.0. This is 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

Simple Tableau Viz versions 2.0 and earlier contain a cross-site scripting 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. An attacker with low-level privileges can craft malicious input that executes in other users' browsers, potentially compromising their sessions or data.
