### 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 Yes this issue has been already fixed in ``` commit e0fe7cc391724fc5baa85b45508f425020fe4272 (HEAD -> master, origin/master) Author: Harshavardhana <> Date: Mon May 27 12:17:46 2024 -0700 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. ### References Refer to the pull request #19810 for more information on the fix.
