CVE-2024-38806

Unauthorized operations via stale shadow-user group membership

Published Jul 18, 2024 · Updated Aug 2, 2024

Authorization failure in UAA 77.10.0 and earlier allows attackers to retain removed group permissions after federated login. External-group reconciliation fails to remove corresponding internal UAA memberships from a shadow user when a later OIDC or SAML assertion omits the group. Exposure requires external-provider group mapping, an administrator's removal of the external membership, and a subsequent login by the affected user.
