Description
An issue was discovered in HashiCorp Vault and Vault Enterprise before 1.11.3. A vulnerability in the Identity Engine was found where, in a deployment where an entity has multiple mount accessors with shared alias names, Vault may overwrite metadata to the wrong alias due to an issue with checking the proper alias assigned to an entity. This may allow for unintended access to key/value paths using that metadata in Vault.

Weakness
CWE-639: Authorization Bypass Through User-Controlled Key
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
How to prevent it
- Architecture and Design: For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
- Architecture and Design, Implementation: Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
- Architecture and Design: Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
