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

🩹 **Official Fix**: **YES**. 📝 **Patch**: Percona/MySQL released patches for `mysqld_safe`. 🔄 **Action**: Update MySQL to patched versions. Apply specific `mysqld_safe` patches to prevent config injection. ✅

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL** (P1). ⚡ **Priority**: Immediate patching required. 📉 **Risk**: Root compromise is game-over for servers. High impact, low barrier to entry (if SQLi exists). 🚨
