CVE-2026-56228Public exploitNetwork attack vectorHinoki check available

Organization-wide lockout via unbounded minimum password length

Published Jun 20, 2026 · Updated Oct 8, 2026

Password-policy validation in Capgo before 12.128.2 allows remote authenticated users to lock out an organization via policy settings. The server accepts an administrator-supplied minimum password length without an upper bound and enforces an impossible requirement against organization members. Organization Admin or Super Admin access and an enabled password policy are required; members, including administrators, lose organization access and cannot complete required password changes.
