I saw these mentioned earlier and could not reproduce either on a stock 2.1.39 install. Looking at the code that handles the "private" endpoint, it's also hard to see a route from the username POST parameter to path construction. Are these vulnerabilities due to modifications made by the vendor (cPanel LLC) to their distributed version? -Valtteri
