Name: Insufficient Verification of Data Authenticity
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 Insufficient Verification of Data Authenticity such that Keycloak's OpenID Connect user authentication was found to incorrectly authenticate requests. An authenticated attacker who could also obtain a certain piece of info from a user request, from a victim within the same realm, can use that data to impersonate the victim and generate new session tokens.
