Polyglot payloads leverage multiple encoding, injection, and obfuscation techniques to bypass filters, confuse parsers, and trigger execution across different contexts like HTML, JavaScript, CSS, JSON, etc.

-Merging Comment Styles

Polyglots often confuse parsers by merging different comment styles:



JavaScript: //, /* */
HTML: 





-Using Encoded Entities

Bypassing filters using HTML or URL encoding:



HTML: <, >, "
URL: , "






<script>alert(1)</script>




-Multiple Language Contexts

Polyglot payloads work across multiple languages like HTML, JavaScript, CSS.
