A flaw was found in the SCIM user listing endpoint of Keycloak, an open-source identity and access management solution. The issue occurs because the endpoint fails to perform per-user VIEW authorization checks when returning user lists. This allows a service account or user with limited query permissions to retrieve full personally identifiable information (PII), such as names and email addresses, for all non-admin users in a realm. This could lead to unauthorized data exposure in environments where the SCIM API is enabled.
