NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-doc package and not the keycloak-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

A flaw was found in Keycloak. An attacker can exploit this vulnerability by modifying the organization ID and target email within a legitimate invitation token's JSON Web Token (JWT) payload. This lack of cryptographic signature verification allows the attacker to successfully self-register into an unauthorized organization, leading to unauthorized access.
