High privilege required to access security settings (PR:H); limited confidentiality and integrity impact reflects policy inconsistency rather than data exfiltration or system takeover; no availability impact to the system itself.
Primary rating from Vendor (VulnCheck).

Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains an authentication logic flaw: a user with permission to manage team or organization security settings can enable mandatory two-factor authentication for all team members without first enabling 2FA on their own account. The application fails to verify the initiator's 2FA status before allowing the policy change, resulting in inconsistent security enforcement, potential administrative misuse, and lockout risk for team members.
AnalysisAI
Authentication logic bypass in Capgo before 12.128.2 permits a team or organization security settings manager to enforce mandatory two-factor authentication across all team members without having 2FA active on their own account. The platform never validates the initiator's own 2FA enrollment state before committing the policy change, creating an asymmetric enforcement condition where the policy creator is effectively exempt from the mandate they impose. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated Capgo user account with explicit permission to manage team or organization security settings (corresponding to PR:H in the CVSS vector). … 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:L/VI:L/VA:N) accurately captures the real-world risk profile: network-reachable but requiring high privileges (PR:H), with limited confidentiality and integrity impact (VC:L/VI:L) and no availability impact to the system itself. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated Capgo team member holding the 'manage security settings' role - but without 2FA configured on their own account - accesses the organization security panel and activates the mandatory 2FA policy. All other team members are immediately subject to the 2FA enrollment requirement and may be locked out of workflows, while the initiating account continues to operate without 2FA, violating the policy it created. … |
| Remediation | Vendor-released patch: Capgo 12.128.2. … Detailed patch versions, workarounds, and compensating controls in full report. |
