What the vulnerability does
The Store Hours for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 4.3.20. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Store Hours for WooCommerce versions up to 4.3.20 contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts. An attacker can craft a malicious link that, when clicked by a site visitor, executes JavaScript in the victim's browser. This can lead to session hijacking, credential theft, or malware distribution. The vulnerability affects the plugin's handling of user input without proper sanitization.
What an attacker can do
Inject and execute malicious JavaScript in visitors' browsers via a crafted link.
Potential impact on your site
Visitors' sessions can be compromised, credentials stolen, or malware injected into your site without your knowledge.
Conditions required to exploit
A site visitor must click an attacker-supplied link while logged into or visiting the affected WooCommerce site.
