Detailed vulnerability description
The vulnerability allows a remote user to modify or delete roles across organizations.
The vulnerability exists due to improper access control in groups_roles.php and RolesService::save() when handling requests for role management actions using a supplied role UUID. A remote privileged user can send a specially crafted request referencing a role UUID from another organization to modify or delete roles across organizations.
Exploitation requires the role administrator right in one organization and knowledge of a target role UUID belonging to another organization on the same installation.
