CVE-2026-124035

What it is

Unsafe reflection in the error mitigation schema validation in Amazon Braket Schemas before 1.32.2 might allow a remote authenticated user with S3 write access to the quantum task output location to execute arbitrary code on any machine that retrieves the quantum task results via a crafted task result document. We recommend you upgrade to amazon-braket-schemas version 1.32.2 or later.
