Summary
ZITADEL is an open source identity management platform. Prior to 3.4.8 and 4.12.2, a vulnerability in Zitadel's Management API has been reported, which allowed authenticated users holding a valid low-privilege token (e.g., project.read, project.grant.read, or project.app.read) to retrieve management-plane information belonging to other organizations by specifying a different tenant’s project_id, grant_id, or app_id. This vulnerability is fixed in 3.4.8 and 4.12.2.
