Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
OpenRemote Manager versions before 1.22.1 are vulnerable to improper access control in the updateUserRealmRoles function. A user holding the write:admin role in one Keycloak realm can change realm roles for users in another realm, including the master realm, because the caller's rights to administer the target realm are not checked. This could let such a user grant themselves or another targeted master-realm user admin rights on the master realm. Upgrade to openremote-manager version 1.22.1 or later.
