Task: a Laravel 10 screenshot/source-view service exposes SSRF in `/api/get-html` because localhost filtering only checks literal IPv4 hosts. Solution: use `localtest.me` plus `gopher://` to push a malicious Redis queue job and reach command injection in `rmFile`, then copy `/flag` into the web root.
