Description
Summary
This notification is related to the use of specific values for the region input field when calling AWS services. An actor with access to the environment in which the SDK is used could set the region input field to an invalid value.
A defense-in-depth enhancement has been implemented in the AWS SDK for Rust. This enhancement validates that a region used to construct an endpoint URL is a valid host label. The change was released on November 6, 2025. This advisory is informational to help customers understand their responsibilities regarding configuration security.
Impact
Customer applications could be configured to improperly route AWS API calls to non-existent or non-AWS hosts. While the SDK was functioning safely within the requirements of the shared responsibility model, additional safeguards have been added to support secure customer implementations.
Impacted versions: All versions prior to November 6, 2025 release
Patches
On November 6, 2025, an enhancement [1] was made to the AWS SDK for Rust release, which validates the formatting of a region, providing additional safeguards.
Workarounds
No workarounds are needed, but as always developers should ensure that their application is following security best practices:
- Implement proper input validation in your application code
- Update to the latest AWS SDK for Rust release on a regular basis
- Follow AWS security best practices [2] for SDK configuration
