❗️ Cheat Sheet for Bypassing Browser XSS Filters

Bypassing a browser's XSS filter is an attempt to bypass security measures that prevent cross-site scripting (XSS) attacks.

These attacks occur when a web application accepts user input into its output without validating or encoding it.

Some ways to bypass XSS filters:
⏺Using weak filters. If they don't cover all possible cases, they can be bypassed.
⏺String construction. For example, if the alert keyword is restricted, the combination "ale" + "rt" will likely not be recognized by the filter.
⏺Using pseudo-protocols. For example, calling JavaScript code from a link.
