Fixed In Version: vault 1.8.0
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in the vault package. The Vault UI web application may fail to completely clear a client-side data cache on user logout. As a result, an authenticated user sharing a browser to access Vault may have been able to view the previous authenticated user’s cached secrets, even if they were not authorized by Vault policies to view them.
