    Keycloak has a Time-of-check Time-of-use (TOCTOU) Race Condition

    CVE-2026-9796 · GHSA-pq65-77rc-7r8c

    Affected
    • Maven org.keycloak:keycloak-server < 26.6.4
    Fixed in
    26.6.4· Vendor fix available
    Issue
    A flaw was found in Keycloak. An authenticated administrator with the manage-clients role can exploit a Time-of-check to time-of-use (TOCTOU) vulnerability in the name-based admin role checks. This allows the attacker to escalate their privileges to realm-admin for all users within the realm, granting them extensive control over the system. The composite role relationship persists even after the attacker's own permissions are revoked and across system reboots.

    Recommended action: Upgrade to 26.6.4 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
