π **Threshold**: LOW. π« **Auth**: No authentication required (PR:N). π±οΈ **UI**: No user interaction needed (UI:N). π **Vector**: Network accessible (AV:N). π **Complexity**: Low (AC:L). Easy to exploit remotely.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: No specific PoC provided in data. π° **References**: WordFence and official changelog link to the issue. π΅οΈ **Status**: Likely exploitable given the low CVSS complexity and network vector.β¦
