Cross-site scripting
Cross-site scripting, or XSS, is a way hackers can trick your browser into running harmful code from a website you trust.
A website can be hacked in many ways. One common method is called cross-site scripting, or XSS. Hackers can inject harmful code into a website's content, like a comment or a login form. When another user visits the site, their browser runs the code without them knowing. This can steal passwords, show fake ads, or redirect them to a fake site.
What it means
Cross-site scripting happens when a website doesn't properly check or clean user input. Hackers can add scripts, often written in JavaScript, to pages that other people visit. These scripts run in the user's browser, making it seem like the code is part of the real website.
Why it matters
XSS attacks can steal sensitive information, like login credentials or payment details. They can also be used to spread malware or trick users into clicking on harmful links. Since the code runs in the browser, users might not realize they're being attacked until it's too late.
What to do
Use a website scanner to check for XSS vulnerabilities. Make sure all user input is properly sanitized and validated. Keep your website and plugins up to date. Avoid using third-party scripts from untrusted sources. If you're unsure, use a free security tool to scan your site.
