This page contains the list of deprecations and important or breaking changes for Vault 1.4.5 compared to 1.4.3. Please read it carefully.
The security updates added in Vault 1.5.1, 1.4.4, 1.3.8, and 1.2.5 include additional header checking during AWS IAM authentication. The default list of allowed headers doesn't include some that are commonly present, which may result in a login error of the form:
Cannot login using AWS-IAM: invalid request header: X-Amz-Security-Token
This issue affects 1.5.2, 1.4.5, 1.3.9, and 1.2.6 as well. It has been corrected in 1.5.3, 1.4.6, 1.3.10 and 1.2.7. The affected released versions can work around the issue by manually configuring the allowed header list, including all needed headers. A recommended configuration is shown below:
vault write auth/aws/config/client \ allowed_sts_header_values="Content-Type" \ allowed_sts_header_values="Content-Length" \ allowed_sts_header_values="User-Agent" \ allowed_sts_header_values="X-Amz-Date" \ allowed_sts_header_values="Authorization" \ allowed_sts_header_values="X-Amz-Security-Token" \ allowed_sts_header_values="Host" \ allowed_sts_header_values="X-Vault-Aws-Iam-Server-Id"
In versions 1.2.6, 1.3.9, 1.4.5, and 1.5.2, the enterprise licenses were not incorporated correctly into the build and we have issued patch releases (x.y.z.1) for enterprise customers containing the proper license. As the previous builds were both not working and causing confusion, we have removed the binaries.
