Amazon S3 Connector Release Notes

These libraries are upgraded to address reported security vulnerabilities:

W-22899430, W-22943408

The Head Object operation now correctly refreshes role-based credentials upon session token expiry. Previously, because Amazon S3 returns a body-less HTTP 400 Bad Request response for HEAD operations, the connector failed to recognize the token expiry, causing subsequent Head Object operations to continuously fail until a different operation triggered a refresh.

W-20190508

The connector now provides diagnostic logs for the credential refresh path and asynchronous execution paths. These logs allow you to monitor latency and retry behavior during security token updates in production environments.

W-18826515

The Get Object operation now prevents file descriptor leaks when Amazon S3 returns 404 (NoSuchKey) error responses. This fix ensures that resources are properly released during exception handling, preventing java.io.IOException: Too many open files errors under high request volumes.

W-21349199

The tooltip for the User metadatas field in the Put Object operation is now updated to clarify that the input for this field in Expression mode supports only inline DataWeave scripts and doesn’t support structured or multiline DataWeave scripts, because they cause XML parsing errors during deployment.
