IP block bypass via predictable unblock keys
Published Dec 13, 2025 · Updated Dec 13, 2025
IP block bypass in Login Lockdown & Protection 2.14 and earlier allows remote attackers to evade lockouts with a crafted unblock key. The $unblock_key value is derived predictably from an administrative email address rather than a sufficiently random secret, allowing generation of a valid key for the attacker's IP address. No account is required, but the administrative email address must be known; success removes the IP lockout and restores login attempts.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
