Name of the Vulnerable Software and Affected Versions MinIO versions prior to RELEASE.2025-04-03T14-56-28Z
Description The issue concerns an authorization flaw in MinIO, a high-performance object storage system. This flaw allows a client with prior WRITE permissions on a bucket to upload objects using any arbitrary secret, given that they have knowledge of the access-key and bucket name. With the necessary information in place, uploading random objects to buckets can be done easily.
Recommendations For versions prior to RELEASE.2025-04-03T14-56-28Z, update to RELEASE.2025-04-03T14-56-28Z or later to resolve the issue. As a temporary workaround, consider restricting WRITE permissions on buckets to minimize the risk of exploitation.
