CVE-2026-16089
MEDIUMKeycloak-services: keycloak-services: authorization codes can be retargeted to another client session
Title source: cnaDescription
A flaw was found in the keycloak-services component of Red Hat Build of Keycloak. The issue occurs because OAuth 2.0 authorization codes are not properly bound to the client that originally requested them. An attacker who can intercept an authorization code can modify it to be redeemed by their own client, potentially allowing them to obtain access tokens for a victim's identity.
