Summary

CVE-2026-40214 is a medium-severity Improper Ownership Management (CWE-282) vulnerability in Launchpad (inferred from references). Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Path Interception (T1034); ranked at the 11th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-16 (Security and Privacy Attributes) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data

In OpenStack Cyborg before 16.0.1, the Accelerator Request (ARQ) API does not enforce project ownership at any layer. The project_id column in the database is never populated (NULL for every ARQ), database queries have no project filtering, and policy checks…

are self-referential (the authorize_wsgi decorator compares the caller's project_id with itself rather than the target resource). Any authenticated non-admin user can complete various actions such as deleting ARQs bound to other projects' instances, aka cross-tenant denial of service.

Mitigating Controls (NIST 800-53 r5) AI

AC-16 Security and Privacy Attributes good match

Security attributes explicitly include ownership, so proper attribute association and management stops incorrect ownership assignment.

AC-3 Access Enforcement good match

Access enforcement requires correct ownership verification before granting access to objects or resources.

AC-24 Access Control Decisions partial match

Access decisions must be based on accurate ownership data for each request.

A.5.15 Access control partial match
degrades

Access control policies can enforce correct ownership assignment and verification for objects.

A.5.16 Identity management partial match
degrades

Identity management processes help ensure objects are assigned to the correct, verified owners.

A.5.18 Access rights partial match

Managing access rights includes verifying and maintaining proper ownership of resources.

A.8.2 Privileged access rights partial match
degrades

Privileged access rights management requires accurate ownership to prevent unauthorized privilege escalation.

A.8.3 Information access restriction partial match
degrades

Information access restriction mechanisms rely on correct ownership to enforce access decisions.

A.8.4 Access to source code partial match
degrades

Access to source code control depends on proper ownership assignment to protect intellectual property.
