CVE-2023-0581Network attack vector

Unauthenticated login-restriction bypass via client-side IP blocking

Published Jan 30, 2023 · Updated Apr 8, 2026

Protection bypass in Aldo Latino PrivateContent 8.4.3 and earlier allows remote attackers to evade IP-based login restrictions. The login anti-bruteforce path checks whether an address is blocklisted in client-side scripts rather than enforcing the decision on the server. No authentication is required; bypassing the browser-side check permits further login attempts from a blocked address, weakening brute-force defenses.
