Q: Who is affected? (Versions/Components)

🏢 **Affected**: zeromicro / go-zero. 📦 **Version**: All versions **before 1.4.4**. If you are running an older Web/RPC framework version, you are at risk.

Q: Is exploitation threshold high? (Auth/Config)

🔓 **Threshold**: **LOW**. CVSS Vector: AV:N (Network), AC:L (Low Complexity), PR:N (No Privileges Required). No authentication or complex configuration is needed to exploit this remotely.

Q: Is there a public Exp? (PoC/Wild Exploitation)

🧪 **Public Exploit**: **No** public PoC or wild exploitation detected in the provided data. However, the logic flaw is clear, making custom exploits highly probable for skilled attackers.

Q: How to self-check? (Features/Scanning)

🔍 **Self-Check**: Check your `go.mod` or dependency tree. If `go-zero` version is `< 1.4.4`, you are vulnerable. Look for configurations where domain filters are user-controllable.

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

✅ **Fixed**: **YES**. Patched in version **1.4.4**. 📝 **Reference**: See GitHub commit `d9d79e9` and GHSA advisory `fgxv-gw55-r5fq` for official details.

Q: Is it urgent? (Priority Suggestion)

⚡ **Urgency**: **HIGH**. CVSS 3.1 indicates severe impact. Since it requires no auth and is network-accessible, patch to v1.4.4 **immediately** to prevent potential bypass attacks.
