CVE-2024-36107

MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. If-Modified-Since and If-Unmodified-Since headers when used with anonymous requests by sending a random object name requests can be used to determine if an object exists or not on the server on a specific bucket and also gain access to some amount of
information such as Last-Modified (of the latest version), Etag (of the latest version), x-amz-version-id (of the latest version), Expires (metadata value of the latest version), Cache-Control (metadata value of the latest version). This conditional check was being honored before validating if the anonymous access is indeed allowed on the metadata of an object. This issue has been addressed in commit e0fe7cc3917. Users must upgrade to RELEASE.2024-05-27T19-17-46Z for the fix. There are no known workarounds for this issue.
