๐ช **Threshold**: **LOW**. <br>๐ **Auth**: None required (PR:N). <br>๐ฑ๏ธ **UI**: No user interaction needed (UI:N). <br>๐ **Network**: Remote (AV:N). <br>โ **Complexity**: Low (AC:L). Easy to exploit! ๐
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ป **Public Exploit**: **No**. <br>๐ **PoC**: None available in the provided data. <br>๐ฎ **Wild Exploitation**: Unlikely currently, but the low barrier makes it highly attractive for future weaponization. โณ
