Magic Variables
Summary: Magic Variables is a Burp Suite extension, authored by Software Secured and at version 1.4.19 as of 02 December 2025, that substitutes placeholders in HTTP traffic with dynamic, static, or predefined values. It is intended to help penetration testers track data flow and generate unique payloads per request, and replacement only applies to traffic that is in scope.
Bottom line: The extension is third-party code that PortSwigger states it makes no warranty about for quality or usefulness, so a testing team adopting it is trusting an outside author's tool inside the same Burp instance that handles in-scope client traffic.
