Q5Is exploitation threshold high? (Auth/Config)
β‘ **Exploitation Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. No authentication (`PR:N`) or user interaction (`UI:N`) required. Network accessible (`AV:N`).
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exploit**: No specific PoC code listed in data. However, references from **Patchstack** confirm the vulnerability class (Arbitrary File Upload). Wild exploitation is likely given low barrier.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **STAGGS** plugin version β€ 2.11.0. Check upload endpoints for lack of strict MIME/extension validation. Use WAF to block `.php` uploads in media folders.
