Assigner: Wordfence

Description
The WPSite Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'format' shortcode attribute in the wpsite_y shortcode and the 'before' attribute in the wpsite_postauthor shortcode in all versions up to, and including, 1.2. This is due to insufficient input sanitization and output escaping in error messages. 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.

Executive Summary

The vulnerability in the WPSite Shortcode plugin for WordPress allows authenticated users with contributor-level access or higher to inject malicious scripts via the 'format' attribute in the wpsite_y shortcode and the 'before' attribute in the wpsite_postauthor shortcode. This happens because the plugin does not properly sanitize input or escape output in error messages, leading to stored Cross-Site Scripting (XSS) attacks that execute whenever a user views the affected page.

Impact Analysis

This vulnerability can allow attackers with contributor-level access to inject arbitrary scripts that execute in the context of users visiting the infected pages. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed on behalf of the victim user without their consent.
