GHSA-XV4R-VCCV-MG4W
Vulnerability from github – Published: 2021-05-24 21:13 – Updated: 2021-12-20 18:07During an internal security audit, we detected an authentication bypass issue in the MinIO admin API. The security issue has been reported internally. We have not observed this exploit in the wild or reported elsewhere in the community at large. All users are advised to upgrade ASAP.
Impact
Given an admin access key, it is possible to perform admin API operations i.e. creating new service accounts for existing access keys without knowing the admin secret key. This security issue was found during a regular internal security audit.
