Vulnerability Data

Minio is a Multi-Cloud Object Storage framework. Affected versions do not correctly honor a `Deny` policy on ByPassGoverance. Ideally, minio should return "Access Denied" to all users attempting to DELETE a versionId with the special header `X-Amz-Bypass-Governance-Retention: true`. However, this…

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

PS-5 Personnel Transfer
addresses: CWE-281

Forces removal or modification of permissions no longer required after reassignment, preventing improper preservation of old access rights.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 mostly match
prevents

Enforcing least-privilege permission policies and reviews directly prevents incorrect permission propagation on copy/restore/share operations.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.15 Access control partial match
degrades

Access-control policy defines how permissions must be preserved when objects are copied or shared.

A.5.18 Access rights partial match
degrades

Access-rights provisioning and review processes directly address the risk of overly permissive copied objects.

A.8.2 Privileged access rights partial match
degrades

Privileged-access management includes rules for maintaining correct permissions on copied or restored data.

A.8.3 Information access restriction partial match
degrades

Information-access-restriction controls enforce least-privilege permissions that must be preserved during copy/restore operations.

A.8.32 Change management none match
none

Change-management procedures can require verification that permissions remain intact after modifications or restores.

A.8.9 Configuration management none match
none

Configuration baselines can embed permission settings, indirectly reducing the chance of incorrect preservation.
