Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains a flaw in the Enforce Password Policy feature: after a Super Admin enables the policy and successfully changes their password to a compliant one, the backend does not update the password-compliance state. As a result, the backend continues to treat the account as non-compliant and repeatedly forces password-reset prompts, permanently locking the Super Admin out of organization access (organization lockout / denial of service) despite valid authentication.
AnalysisAI
Capgo's Enforce Password Policy feature in versions before 12.128.2 permanently locks Super Admins out of their organization through a backend state management flaw, constituting a targeted denial-of-service against administrative access. When a Super Admin enables the password policy and successfully changes their password to a policy-compliant value, the backend fails to mark the account compliant, trapping the account in an infinite forced-password-reset loop and severing all organization management access. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The vulnerability requires two specific conditions: (1) the Enforce Password Policy feature must be explicitly enabled within the Capgo organization by a Super Admin, and (2) the Super Admin must subsequently perform a compliant password change through the policy-driven reset flow. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N, score 6.9) accurately models the key risk trade-off: network accessibility with low complexity, but gated behind Super Admin privileges (PR:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A Super Admin navigates to the Capgo organization settings, enables Enforce Password Policy, and proceeds through the mandated password-change flow, entering a new password that meets all policy requirements. The backend accepts the password as valid but fails to flip the compliance flag, so every subsequent login attempt immediately redirects the admin to the password-reset prompt. … |
| Remediation | Upgrade Capgo to version 12.128.2 or later, which resolves the backend compliance-state update failure per vendor GitHub Security Advisory GHSA-78rv-3cqj-36xq (https://github.com/Cap-go/capgo/security/advisories/GHSA-78rv-3cqj-36xq). … Detailed patch versions, workarounds, and compensating controls in full report. |
