What the vulnerability does
The Booster for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 7.1.7 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
A validation flaw in Booster for WooCommerce allows authenticated users with low privileges to read sensitive data and modify site content across different areas. The vulnerability stems from insufficient input validation and scope crossing. Attackers need a valid WordPress account but no special role. Update to a version newer than 7.1.7.
What an attacker can do
Read sensitive data and modify site content as an authenticated low-privilege user.
Potential impact on your site
Authenticated users can access and alter data beyond their intended permissions, affecting site integrity and confidentiality.
Conditions required to exploit
