SCA: security update for github.com/minio/minio (GHSA-jjjj-jwhf-8rgr)

high Tenable Cloud Security Plugin ID 435645

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - MinIO is a high-performance object storage system. In all versions prior to RELEASE.2025-10-15T17-29-55Z,
 a privilege escalation vulnerability allows service accounts and STS (Security Token Service) accounts
 with restricted session policies to bypass their inline policy restrictions when performing operations on
 their own account, specifically when creating new service accounts for the same user. The vulnerability
 exists in the IAM policy validation logic where the code incorrectly relied on the DenyOnly argument when
 validating session policies for restricted accounts. When a session policy is present, the system should
 validate that the action is allowed by the session policy, not just that it is not denied. An attacker
 with valid credentials for a restricted service or STS account can create a new service account for itself
 without policy restrictions, resulting in a new service account with full parent privileges instead of
 being restricted by the inline policy. This allows the attacker to access buckets and objects beyond their
 intended restrictions and modify, delete, or create objects outside their authorized scope. The
 vulnerability is fixed in version RELEASE.2025-10-15T17-29-55Z. (CVE-2025-62506)
