Pagekit CMS version 1.0.18 has a privilege escalation vulnerability that allows authenticated users with the 'user: manage users' permission to assign arbitrary custom roles to themselves. This occurs due to missing authorization checks in the UserApiController::saveAction() method. Exploiting this flaw, attackers can grant themselves a custom role with the 'system: manage packages' permission, enabling them to upload and install malicious PHP packages via the admin package installer, potentially leading to remote code execution.
