Upgrade org.keycloak:keycloak-services to version 26.5.4 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 Incorrect Behavior Order: Authorization Before Parsing and Canonicalization due to the Authorization header parser accepting non-standard characters as separators and tolerating case variations that do not comply with RFC 6750 specifications. An attacker can bypass intended access restrictions by crafting specially formatted authentication headers.
