⚡ A sneaky remote command execution is hiding in zrlog 2.2.2, lurking in the avatar upload function! 🎭 Think of it like a restaurant kitchen that lets you submit your own recipe without ever checking the ingredients. If the chef isn’t careful, you could end up with a dish that’s not only not on the menu, but could also ruin everyone’s meal! If exploited, an attacker could upload a JSP file disguised as an avatar, giving them a WebShell and complete control over the server. This opens the door for data breaches, unauthorized access, and a whole world of chaos!
