Stored Cross-Site Scripting Vulnerability in Team Showcase Plugin for WordPress

CVE-2023-5639

Summary

The Team Showcase plugin for WordPress is susceptible to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping on user-supplied attributes in the 'tmfshortcode' shortcode. Authenticated attackers with contributor-level permissions or above can exploit this weakness, allowing them to inject arbitrary scripts into web pages. When a user accesses these affected pages, the scripts will execute, potentially leading to unauthorized access or data manipulation. This security flaw emphasizes the need for robust validation and sanitization methods in web application development.
