Overview
rustfs is a high-performance distributed object storage software built using Rust, one of the most popular languages worldwide. Along with MinIO, it shares a range of advantages such as simplicity, S3 compatibility, open-source nature, support for data lakes, AI, and big data. Furthermore, it has a better and more user-friendly open-source license in comparison to other storage systems, being constructed under the Apache license.
Affected versions of this package are vulnerable to Incorrect Privilege Assignment via the ImportIam process. An attacker can gain unauthorized access to modify IAM entities by exploiting improper authorization checks that validate export permissions instead of import permissions.
