Minio · Minio · CVE-2023-28433
**Name of the Vulnerable Software and Affected Versions**
Minio versions prior to RELEASE.2023-03-20T20-16-18Z
**Description**
The issue is related to insufficient access control in Minio, a Multi-Cloud Object Storage framework. Minio fails to filter the `` character, which allows for arbitrary object placement across buckets. As a result, a user with low privileges, such as an access key, service account, or STS credential, which only has permission to `PutObject` in a specific bucket, can create an admin user.
**Recommendations**
For versions prior to RELEASE.2023-03-20T20-16-18Z, update to RELEASE.2023-03-20T20-16-18Z or later to resolve the issue.
At the moment, there are no known workarounds for this issue.
