AI description

Automated description summarized from trusted sources.

CVE-2025-66467 describes a vulnerability within Apache CloudStack related to MinIO policy cleanup. The issue arises when MinIO policies are not properly removed after a bucket is deleted via Apache CloudStack. This oversight allows former owners of a bucket to retain their access permissions. Consequently, if a new bucket is subsequently created with the identical name, the previous owners can exploit their retained access and secret keys to gain unauthorized read and write access to the newly created bucket. Users are advised to update to Apache CloudStack versions 4.20.3.0 or 4.22.0.1, or later, to address this vulnerability.

Description: Missing MinIO policy cleanup on bucket deletion via Apache CloudStack allows users to retain access to buckets which they previously owned. If another user creates a new bucket with the same name, the previous owners can gain unauthorized read and write access to it by using the previously generated access and secret keys. Users are recommended to upgrade to Apache CloudStack versions 4.20.3.0 or 4.22.0.1, or later, which fixes this issue.
