CVE-2026-56228
CWE-20Published: June 20, 2026· Updated: Jun 23, 2026
Official Description
Capgo before 12.128.2 fails to enforce a maximum value on the minimum password length field in its password policy configuration. An authenticated organization administrator can set an extremely large numeric value (e.g., billions of characters) as the minimum password length, making compliance impossible for all organization members. Once the policy is enabled, users (including administrators) are unable to change their passwords or access the organization, resulting in an organization-wide account lockout and application-level denial of service.
Technical Analysis
CVE-2026-56228 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in availability disruption (denial of service), with a CVSS base score of 4.9.
