Vulnerability Title
StudioCMS: IDOR — Admin-to-Owner Account Takeover via Password Reset Link Generation
Source: CVE Program / CVE List V5
Vulnerability Description
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.
