CVE-2026-7504 (opens in a new tab)How to fix?
Upgrade org.keycloak:keycloak-services to version 26.6.2 or higher.
Overview
org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Open Redirect through the areWildcardsAllowed check in RedirectUtils. An attacker can bypass redirect URI validation by supplying a redirect URI with an unparsed authority component and wildcard patterns, thereby sending users to an attacker-controlled destination.
Notes
- Clients only become vulnerable when their
Valid Redirect URIsinclude a wildcard (*); exact-match redirect URI configurations are not affected by this bypass. - Exploitation depends on a malformed redirect URI whose authority cannot be parsed cleanly by Java’s
URIhandling, such as one using multiple@characters in the user-info portion.
