@dhvakr thank you for contributing the reference link and @abstractj thank you for confirming that adding the reference link is a change that looks good to you! I read keycloak/keycloak@9d9817e (and keycloak/keycloak@e3598a5 for version 22.0.10) and agree that these look like they make changes that would fix GHSA-m6q9-p373-g5q8.
