AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in MinIO allows service accounts and STS accounts with restricted session policies to bypass their policy restrictions when performing operations on their own account. Specifically, due to incorrect IAM policy validation logic, an attacker with valid credentials can create a new service account for themselves that inherits full parent privileges instead of being restricted. This means the attacker can access and modify buckets and objects beyond their authorized scope.
How can this vulnerability impact me? :
The vulnerability can lead to privilege escalation, allowing an attacker to gain unauthorized access to buckets and objects, and to modify, delete, or create objects outside their intended permissions. This can compromise data integrity and confidentiality within the MinIO object storage system.
What immediate steps should I take to mitigate this vulnerability?
Upgrade MinIO to version RELEASE.2025-10-15T17-29-55Z or later, as this version contains the fix for the privilege escalation vulnerability. Until the upgrade is applied, restrict the use of service accounts and STS accounts with restricted session policies to minimize risk.
