Q4What can hackers do? (Privileges/Data)
🕵️ **Capabilities**: High Impact (CVSS H). Attackers can achieve **Code Execution**, **Data Theft**, and **System Modification**. Full control over the WordPress environment is possible.
Q5Is exploitation threshold high? (Auth/Config)
🔓 **Threshold**: Low. CVSS Vector: AV:N/AC:L/PR:N/UI:N/S:U. No authentication (PR:N) or user interaction (UI:N) required. Remote exploitation is trivial.
Q6Is there a public Exp? (PoC/Wild Exploitation)
📜 **Public Exp**: No specific PoC listed in the provided data. However, the nature of Object Injection often allows for generic exploit chains. Caution advised.
Q7How to self-check? (Features/Scanning)
🔍 **Self-Check**: Scan for 'Extreme Store' theme. Check version number. Look for deserialization functions handling user input. Use WPScan or similar tools.
Q8Is it fixed officially? (Patch/Mitigation)
