Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Keycloak ausnutzen, um Sicherheitsvorkehrungen zu umgehen und Daten zu manipulieren.

Editorial Analysis

What to do

Prioritise Keycloak patching, rotate signing keys if token forgery is in scope, and review OIDC client configurations for least-privilege scopes.
