AI-suggested
Upgrade StudioCMS to version 0.4.0 or later, where the authorization checks on the /studiocms_api/dashboard/api-tokens endpoint have been properly implemented. Until upgrading, restrict Editor-level user privileges to trusted personnel only and monitor API token creation logs for suspicious activity. Implement network segmentation and access controls to limit exposure of the CMS API endpoints. Employ Web Application Firewalls (WAFs) with custom rules to detect and block anomalous API token generation requests. Conduct regular audits of user roles and API tokens to identify unauthorized privilege escalations. Additionally, consider implementing multi-factor authentication (MFA) for all users with elevated privileges to reduce the risk of compromised credentials being exploited.
Description
StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.4.0, the /studiocms_api/dashboard/api-tokens endpoint allows any authenticated user (at least Editor) to generate API tokens for any other user, including owner and admin accounts. The endpoint fails to validate whether the requesting user is authorized to create tokens on behalf of the target user ID, resulting in a full privilege escalation. This vulnerability is fixed in 0.4.0.
