HTTP is supposed to be stateless, but sometimes... it isn't! Some servers create invisible vulnerabilities by only validating the first request on each TCP/TLS connection. I've just published a Custom Action to help you detect & exploit this - here's a narrated demo: youtu.be/BAZ-z2fA8E4

Imagine you have a XSS vulnerability but you have a undefined variable before your injection. Is all hope lost? Not at all you can use a technique called XSS Hoisting to declare the variable and continue your exploit. Thanks to ycam_asafety for the submission. portswigger.net/web-security...

"This strategy creates an avalanche of desync research leads" is somehow an understatement. Take Smuggler for a spin on your largest burp file right now and just watch the issue counter 🔥. If you want even more results, adding new headers / perms looks to be trivial (it's one line of code).
