[UPDATE] [mittel] Keycloak (netty-codec-http): Schwachstelle ermöglicht Manipulation von Dateien

Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Keycloak ausnutzen, um Dateien zu manipulieren.

Editorial Analysis

Why it matters

Keycloak underpins SSO and identity federation for many European enterprises; a file-manipulation path in its HTTP codec layer could let attackers tamper with authentication assets.

What to do

Patch Keycloak to the latest release and audit reverse-proxy rules filtering malformed HTTP requests to the Keycloak endpoint.
