CVE-2026-64798Network attack vector

Account access via predictable persistent URL keys

Published Jul 22, 2026 · Updated Jul 22, 2026

Weak URL-key generation in Regular Labs IP Login 1.0.0 through 6.2.5 allows remote attackers to predict keys and access user accounts. The persistent URL login-key generator uses a non-cryptographic random generator with insufficient entropy, producing predictable secrets; function-level details are not public. Exploitation requires an account configured for IP Login and a request that satisfies its IP-address check, after which the predicted key authenticates the attacker as that account.
