CVE-2026-97147Network attack vectorHinoki check available

Cross-project corruption via unscoped API writes

Published Oct 8, 2026 · Updated Oct 8, 2026

Authorization bypass in OpenStack Mistral's v2 API allows remote authenticated users to overwrite other projects' public resources. Write paths resolve targets using queries that return another project's resources, allowing project members to rewrite and un-publish public action definitions and environments. API exposure is required; project administrators can also submit workbooks with colliding embedded action or workflow names to transfer resources into their project and make the original owner's updates fail with server errors.
