What the vulnerability does
The Loco Translate plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘update_href’ parameter in all versions up to, and including, 2.8.2 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
Loco Translate versions 2.8.2 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the application. The vulnerability requires user interaction—such as clicking a malicious link—and can affect other users or the site itself. An attacker with no authentication can exploit this to steal session tokens, deface content, or redirect users to phishing sites.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they visit a crafted link.
Potential impact on your site
Users' sessions could be compromised, site content could be defaced, or visitors redirected to malicious sites.
Conditions required to exploit
Victim must click a malicious link or visit an attacker-controlled page; no authentication required.
