Authenticated privilege escalation via unrestricted role updates
Published Dec 17, 2025 · Updated Dec 17, 2025
Authorization bypass in Pagekit CMS 1.0.18 allows remote authenticated users to escalate privileges through default-role updates. The /api/user/role/bulk endpoint accepts an authorized POST with cookies and an XSRF token, then saves attacker-selected names and permissions for existing default roles without server-side restrictions. Any account able to submit that request can alter the Anonymous, Administrator, or Authenticated roles and elevate its privileges.
