Kerentanan Improper Validation of Consistency within Input pada redhat build of keycloak. Skor CVSS 3.1 5.5 (Medium) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in the Keycloak keycloak-services component, which handles the management of identity providers. The issue occurs when a delegated administrator updates an OIDC identity provider using a masked client secret sentinel value. Due to improper validation, Keycloak reuses the existing real secret even if security-sensitive fields like the token URL have been changed, allowing an attacker to redirect and capture the secret.
