  1. [medium] A user with write permissions to a portion of a repository may use the S3 gateway to copy any object in the repository if they know its name.
  2. [medium] A user with permission to write any one of tags, branches, or commits on a repository may write all of them.
  3. [low] A user with permission to read any one of tags, branches, or commits on a repository may read all of them.
  4. [low] A user allowed to list objects in a repository or read repository meta-data may retrieve graveler information about the location on underlying storage of all objects stored in any commit that they can view.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
