GHSA-95fr-cm4m-q5p9: MinIO information disclosure vulnerability
Impact
If-Modified-Since If-Unmodified-Since
Headers when used with anonymous requests by sending a random object name requests you can figure out if the 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.
Patches

fix: information disclosure bug in preconditions GET (#19810)
precondition check was being honored before, validating
if anonymous access is allowed on the metadata of an
object, leading to metadata disclosure of the following
headers.
```
Last-Modified
Etag
x-amz-version-id
Expires:
Cache-Control:
```
although the information presented is minimal in nature,
and of opaque nature. It still simply discloses that an
object by a specific name exists or not without even having
enough permissions.
Users must upgrade to RELEASE.2024-05-27T19-17-46Z for the fix
Workarounds
There are no workarounds.
