Who should care
Administrators and security teams of organizations using Capgo, especially those with multiple organizations configured, should be aware of this vulnerability. The ability to disrupt user accounts across organizations could lead to significant operational impact and potential security risks if exploited.
Technical summary
The vulnerability is caused by insufficient access controls in the SSO prelink endpoint of Capgo. An attacker with 'org.update_settings' permission can make unauthorized changes to user authentication methods across organizations. This is possible because the endpoint does not properly validate the organization context of the users being modified. The CVSS score for this vulnerability is 7.2, indicating a high severity level.
Defensive priority
Given the high severity and potential for cross-organizational impact, defensive actions should be prioritized. Organizations using Capgo should review their configurations and user permissions immediately.
Recommended defensive actions
- Review and restrict 'org.update_settings' permissions to trusted administrators.
- Monitor SSO provider configurations and user authentication changes.
- Implement additional logging and monitoring for the SSO prelink endpoint.
- Consider temporarily disabling the SSO prelink feature until a patch is applied.
- Enforce strong password policies and multi-factor authentication.
