WordPress Team Showcase Plugin DOM-Based Cross-Site Scripting Vulnerability

A DOM-based cross-site scripting vulnerability has been identified in the WordPress Team Showcase plugin, affecting versions prior to 25.05.13.

Impact

Exploitation of this vulnerability allows for cross-site scripting, where injected scripts are executed in the context of the user's browser. This could lead to the injection of malicious payloads, such as redirects or advertisements, which would be executed when visitors access the affected site.
