CVE-2026-93856In OpenStack Cinder through 29.0.0, cross-project information disclosure can occur in the Messages API Executive summary A flaw in OpenStack Cinder's Messages API allowed a non-admin user with only the project-scoped reader or member role to see user messages belonging to other projects, including resource UUIDs. The advisory rates the issue Medium in its original report, and the advisory does not state a final severity score. The vendor's fix is a code change that limits message queries to the caller's own project, and fixed releases are listed for several stable branches. Technical summary This is a cross-project information disclosure caused by a missing project filter in the Cinder message list path (GET /v3/messages), where the default for project_only in _messages_get_query was False. The attack requires only a valid project-scoped member or reader account on any project, with no admin rights or user interaction. The advisory lists affected versions as >=9.0.0 <26.3.1, ==27.0.0, ==28.0.0 and ==29.0.0, and the fix is in master and the stable/2026.2, stable/2026.1, stable/2025.2 and stable/2025.1 branches, plus unmaintained/2024.1, with the default changed to project_only=True. The advisory does not state a specific fixed version number for each branch, nor any workaround. No detection guidance or evidence of exploitation in the wild is stated.
