Timeline

2026-07-30	first spoke of it: keycloak-services: keycloak-services: Full-scope-disabled client policy validation bypass via omitted fullScopeAllowed	Red Hat
2026-08-02	first spoke of it: A flaw was found in the full-scope-disabled client-policy executor within the keycloak-services component. This component is responsible for enforcing security policies during client registration and configuration in Red Hat Build of Keycloak. The issue occurs because the executor only validates the fullScopeAllowed field when it is explicitly provided in a request. By omitting this field, a delegated user can bypass the policy, resulting in a client created with full scope access. This allows the client to obtain tokens with unauthorized role mappings.	NVD

What it is to other things

affects	redhat/build_of_keycloak NVD
made_by	redhat NVD

In words only, so not counted until a person confirms one:

made_by	`red_hat` NVD says “Red Hat”
affects	`red_hat/red_hat_build_of_keycloak_26_6` NVD says “Red Hat · Red Hat build of Keycloak 26.6”
