๐ **Threshold**: Medium. <br>โ **Auth Required**: Yes, **Authenticated** access needed. <br>โ๏ธ **Config**: Low complexity (AC:L). No user interaction required (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **Exploit Status**: Public PoC available on GitHub (TREXNEGRO). <br>โ ๏ธ **Risk**: Easy to reproduce. Wild exploitation is likely given the simplicity.
Q7How to self-check? (Features/Scanning)
