πŸ›‘ **Workaround**: If you can't upgrade, **disable** the `panel.adminmail` input field or restrict admin access via WAF/Network ACLs. 🚫 **Block**: Prevent admin panel access from untrusted networks.

Q10Is it urgent? (Priority Suggestion)

πŸ”₯ **Urgency**: **HIGH**. 🚨 **Priority**: Critical. Even though it needs auth, the impact is **Root RCE**. Patch immediately upon upgrade to 2.3.4.
