MEDIUM4.3

A vulnerability was discovered in Keycloak's Admin UI extension that allows certain administrative users to bypass security restrictions. When Fine-Grained Admin Permissions (FGAPv2) are enabled, an administrator who should only be able to search for users (but not view their full details) can use a specific "brute-force-user" endpoint to access a user's full profile. This includes sensitive information and security metadata. The issue occurs because the system fails to check if the administrator has the required "view" permission for that specific user when using this particular search path.

MEDIUM5.4

A flaw was found in the ClientResource component of Keycloak's admin services when Fine-Grained Admin Permissions (FGAP) v2 is enabled. This issue allows a delegated administrator, who should only have limited control over specific clients, to attach or remove hidden client scopes that they are not authorized to see or manage. As a result, an attacker could inject unauthorized data or permissions into the security tokens issued to end-users, potentially tricking other applications into granting higher levels of access than intended.

MEDIUM4.3

A flaw was found in the Fine-Grained Admin Permissions (FGAP) v2 implementation within Keycloak's administrative services. When FGAP v2 is enabled, the system fails to properly filter child groups based on the caller's specific permissions when requested through a parent group. This allows a delegated administrator to view details of child groups they are not authorized to access directly, including group names, paths, and custom attributes.

MEDIUM6.5

A flaw was found in Keycloak. A highly privileged user with `manage-clients` permission can exploit this vulnerability by injecting a hardcoded role mapper into any client. This action allows the user to bypass existing scope restrictions and inject the `realm-admin` role into generated tokens, resulting in privilege escalation and full administrative access to the realm.

HIGH7.5

A flaw was found in Keycloak. When a JSON Web Encryption (JWE) encrypted request object is submitted, Keycloak may incorrectly process unsigned claims if the decrypted content is raw JSON, bypassing the configured signature policy. This allows a remote attacker to submit unauthorized claims, leading to a compromise of data integrity within the OpenID Connect (OIDC) authorization flow. While a redirect URI allowlist acts as a compensating control, this vulnerability violates OIDC Core and Financial-grade API (FAPI) signing requirements.
