The vulnerability allows a remote user to perform a denial of service attack.
The vulnerability exists due to the way the application handles authentication based on Approle SecretID. A remote user with access to the "/auth/approle/role/:role_name/secret-id-accessor/destroy" endpoint can destroy the secret ID of any other role by providing the secret ID accessor and disable access to Vault for other users.Remediation
