CVE-2026-74250Network attack vectorHinoki check available

Cross-tenant data disclosure via skipped node cleaning

Published Aug 14, 2026 · Updated Aug 14, 2026

Data exposure in OpenStack Ironic 32.0.0 through 35.0.1 and 36.0.0 through 38.0.0 allows remote authenticated users to read prior tenant data. When a node is enrolled with or changed to autodetect, the deploy-interface transition is not preserved through cleaning, so automated disk erasure can be skipped. An authenticated tenant must receive such a node before another cleaning cycle; the bounded consequence is disclosure of residual storage data.
