A defense-in-depth enhancement has been implemented to improve handling of special characters, such as double quotes and backslashes, in input values.\n\n### Impact\n\nThe 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.\n\n### Impacted versions: 3.11.7 - 3.371.3\n\n### Patches\n\nOn 3/3/2026, an enhancement was made to the AWS SDK for PHP version 3.371.4.
