CVE-2026-32106 Details
Description
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.
A vulnerability in StudioCMS versions prior to 0.4.3 allows for privilege escalation through inconsistent user rank checks in the REST API. The createUser endpoint only prevents the creation of owner accounts, while the Dashboard API correctly blocks the creation of users at or above the admin's rank. This inconsistency enables an admin to create additional admin accounts via the REST API, facilitating privilege proliferation and persistence.
Users can update to StudioCMS version 0.4.3 or later, where this vulnerability has been fixed.
