## Overview

### Impact
[If-Modified-Since](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/If-Modified-Since)
[If-Unmodified-Since](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/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
Yes this issue has been already fixed in

    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
