CVE-2026-32131Network attack vector

Cross-tenant data disclosure via unchecked resource identifiers

Published Mar 11, 2026 · Updated Mar 11, 2026

Information disclosure in ZITADEL before 3.4.8 and 4.0.0 through 4.12.1 allows remote authenticated users to read cross-tenant data. Management API lookup endpoints accepted attacker-supplied project, grant, application, or user identifiers without asserting that the retrieved resource belonged to the selected organization. A low-privilege token with a listed read permission and knowledge or enumeration of a target identifier exposes OIDC client IDs, redirect URIs, allowed origins, and other management-plane information.
