What the vulnerability does
The LiteSpeed Cache plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URLs in all versions up to, and including, 7.5.0.1 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
LiteSpeed Cache versions up to 7.5.0.1 contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into web pages. The vulnerability requires user interaction—typically clicking a malicious link—and can affect other users viewing the compromised page. An attacker with no authentication can exploit this to steal session cookies, redirect users, or deface content.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they visit an affected page.
Potential impact on your site
Visitors' browsers can be compromised; session tokens, credentials, or personal data may be stolen or site content defaced.
Conditions required to exploit
Victim must click a malicious link or visit a page containing the attacker's payload. No authentication required.
