Summary
AWS SDK for Java 2.0: Improper Handling of Special Characters in CloudFront Signing Utilities
Details

Summary

This notification is related to the CloudFront signing utilities in the AWS SDK for Java v2, which are used to generate Amazon CloudFront signed URLs and signed cookies. A defense-in-depth enhancement has been implemented to improve handling of special characters, such as double quotes and backslashes, in input values.

Impact

The CloudFront signing utilities build policy documents that define access restrictions for signed URLs and cookies. If an application passes unsanitized input containing special characters to these utilities, the resulting policy document may not reflect the application's intended access restrictions. While the SDK was functioning safely within the requirements of the shared responsibility model, additional safeguards have been added to support secure customer implementations. Applications that already follow AWS security best practices for input validation are not impacted.

Impacted versions:

2.18.33 - 2.41.29

Patches

On 2026.02.16, an enhancement was made to AWS SDK for Java v2 version 2.41.30. The enhancement ensures that special characters in input values are correctly handled. We recommend upgrading to the latest version.

Workarounds

No workarounds are needed, but customers should ensure that your application is following security best practices:
