    Keycloak: Denial of Service due to excessive SAMLRequest decompression

    CVE-2026-2575 · GHSA-xv6h-r36f-3gp5

    Affected
    • Maven org.keycloak:keycloak-saml-adapter-core < 26.5.4
    Fixed in
    26.5.4· Vendor fix available
    Issue
    A flaw was found in Keycloak. An unauthenticated remote attacker can trigger an application level Denial of Service (DoS) by sending a highly compressed SAMLRequest through the SAML Redirect Binding. The server fails to enforce size limits during DEFLATE decompression, leading to an OutOfMemoryError (OOM) and subsequent process termination. This vulnerability allows an attacker to disrupt the availability of the service.

    Recommended action: Upgrade to 26.5.4 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
