Vulnerabilidades de Withstudiocms

StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.4.3, the REST API createUser endpoint uses string-based rank checks that only block creating owner accounts, while the Dashboard API uses indexOf-based rank comparison that prevents creating users at or above your own rank. This inconsistency allows an admin to create additional admin accounts via the REST API, enabling privilege proliferation and persistence. This vulnerability is fixed in 0.4.3.

StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.4.3, the POST /studiocms_api/dashboard/create-reset-link endpoint allows any authenticated user with admin privileges to generate a password reset token for any other user, including the owner account. The handler verifies that the caller is an admin but does not enforce role hierarchy, nor does it validate that the target userId matches the caller's identity. Combined with the POST /studiocms_api/dashboard/reset-password endpoint, this allows a complete account takeover of the highest-privileged account in the system. This vulnerability is fixed in 0.4.3.

StudioCMS is a server-side-rendered, Astro native, headless content management system. Prior to 0.4.0, the DELETE /studiocms_api/dashboard/api-tokens endpoint allows any authenticated user with editor privileges or above to revoke API tokens belonging to any other user, including admin and owner accounts. The handler accepts tokenID and userID directly from the request payload without verifying token ownership, caller identity, or role hierarchy. This enables targeted denial of service against critical integrations and automations. This vulnerability is fixed in 0.4.0.

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.
