An attacker who can supply that input can get code execution on the machine running the SDK. _Summary, check and fix written by a model from the sources; labelled as such._ ## Affected - pypi:amazon-braket-sdk affected >= 1.10.0, < 1.117.0 fixed 1.117.0 ## How to check - Run `pip show amazon-braket-sdk` and compare the version with the affected range (>= `1.10.0`, < `1.117.0`). - Check whether your code or jobs read data from S3 locations that other principals can write to, since the bulletin points there for the related CVEs. ## Fix - amazon-braket-sdk (PyPI): upgrade to `1.117.0`. ## Timeline - 2026-11-09T23:46:36+00:00 lab https://aws.amazon.com/security/security-bulletins/rss/2026-175-aws/ — AWS: CVE-2026-124034, CVE-2026-124035: Issues with Amazon Braket SDK - 2026-11-09T23:48:20+00:00 ghsa https://github.com/advisories/GHSA-g697-2xrc-gc46 - 2026-11-10T00:28:47+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-9291 ## Documents - [advisory] Maintainer's advisory: api.github.com https://api.github.com/repos/amazon-braket/amazon-braket-sdk-python/security-advisories/GHSA-g697-2xrc-gc46 - [advisory] Maintainer's advisory: github.com https://github.com/amazon-braket/amazon-braket-sdk-python/security/advisories/GHSA-g697-2xrc-gc46 - [fix] Release: github.com https://github.com/amazon-braket/amazon-braket-sdk-python/releases/tag/v1.117.0 - [mentions] AWS: CVE-2026-124034, CVE-2026-124035: Issues with Amazon Braket SDK https://aws.amazon.com/security/security-bulletins/rss/2026-175-aws/ ## From the sources CVE-2026-124034, CVE-2026-124035: Issues with Amazon Braket SDK ### CVE-2026-124034, CVE-2026-124035: Issues with Amazon Braket SDK Bulletin ID: 2026-175-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 11/09/2026 14:15 PM PST Description: Amazon Braket SDK is an open source Python library that customers use to run quantum tasks and hybrid jobs on Amazon Braket and retrieve their results, and it uses the Amazon Braket Schemas library to parse task results. We identified CVE-2026-124034, an issue in the local hybrid job input data download in the Amazon Braket SDK. A remote authenticated user with S3 write access to a hybrid job's input data location might be able to overwrite arbitrary files, with the privileges of the user running the job, by supplying crafted S3 object keys. We identified CVE-2026-124035, an issue in the error mitigation schema validation in Amazon Braket Schemas, the library the Amazon Braket SDK uses to parse quantum task results. A remote authenticated user with S3 write access to the quantum task output location might be able to execute arbitrary code on any machine that retrieves the quantum task results by supplying a crafted task result document. Please note, this is a follow-on fix to the prior advisory CVE-2026-9291. Impacted versions: - CVE-2026-124034: amazon-braket-sdk >= 1.10.0 AND < 1.127.7 - CVE-2026-124035: amazon-braket-schemas >= 1.17.0 AND < 1.32.2 Resolution: - CVE-2026-124034: This issue has been addressed in Amazon Braket SDK version 1.127.7. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes. - CVE-2026-124035: This issue has been addressed in Amazon Braket Schemas version 1.32.2. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes. Workarounds: Restrict S3 write access to the Braket task-output and local-job input data locations (and the job's IAM role) to trusted principals.
