CVE-2024-13581: Simple Charts <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting
Description
The Simple Charts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'simple_chart' shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes.
