Q: Is it fixed officially? (Patch/Mitigation)

✅ **Fixed**: **YES**. Official patch released. 📦 **Solution**: Upgrade to version **18.2.40.1683** or later. 🔄 **Action**: Immediate update required for all affected instances.

Q: What if no patch? (Workaround)

🚧 **No Patch?**: Block external access to `/public/login.htm`. 🛑 **Mitigation**: Restrict network access to PRTG web interface. 🚫 **Workaround**: Disable public access if internal-only monitoring is sufficient.

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL**. 🚨 **Priority**: **P1**. Remote unauthenticated admin creation is a game-over scenario. Patch immediately to prevent total network compromise.
