Impact

CVE-2026-55670 is a cross-tenant user data leakage issue in ZITADEL arising from recycled user identifiers, fixed upstream in 4.15.2 (GHSA-6x8v-2fq5-2229). The vulnerable code path is present in this package, which tracks the ZITADEL v3 stream (v3.4.13). The fix is available only in the v4 release line; no v3 backport has been released. The upstream remediation is a cross-cutting change (new database migration and eventstore changes) specific to the v4 line. References: NVD CVE-2026-55670; GHSA-6x8v-2fq5-2229.
