ZITADEL: Cross-Tenant User Leakage via Recycled Identifiers

Description

ZITADEL is an open source identity management platform. Prior to 4.15.1, ZITADEL's event store validation can retain the original resource owner for a deleted user identifier, causing a later user recreated with the same identifier in another organization to be provisioned under the original organization and exposed to that organization's administrator. This issue is fixed in version 4.15.2.
