What the vulnerability does
The Yoast SEO plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URLs in all versions up to, and including, 22.5 due to insufficient input sanitization and output escaping. 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
Yoast SEO versions 22.5 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the site. An attacker can craft a malicious link or page that, when visited by a site administrator or user, executes arbitrary JavaScript in their browser. This can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim.
What an attacker can do
Inject and execute malicious JavaScript in a user's browser when they visit a crafted page or link.
Potential impact on your site
Administrators or users visiting malicious links could have their sessions hijacked, credentials stolen, or site settings modified without their knowledge.
Conditions required to exploit
The victim must visit a page or click a link controlled or crafted by the attacker. No special privileges required.
