x8
High-signal hidden parameter discovery in Rust. Detects reflected, stored, and behavior-changing params with fewer false positives than brute forcers.
Overview
Where x8 fits
High-signal hidden parameter discovery in Rust. Detects reflected, stored, and behavior-changing params with fewer false positives than brute forcers.
Detection-first use
Start with the least intrusive template that can distinguish your hypothesis from a normal response. Preserve raw output and a negative control.
