CVE-2026-15943
5.5
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:N
Summary
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.
