CVE-2025-1391 Information

Description

A flaw was found in the Keycloak organization feature which allows the incorrect assignment of an organization to a user if their username or email matches the organization’s domain pattern. This issue occurs at the mapper level leading to misrepresentation in tokens. If an application relies on these claims for authorization it may incorrectly assume a user belongs to an organization they are not a member of potentially granting unauthorized access or privileges.
