Summary

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.

Inferred packages

No advisory lists a package for this vulnerability yet. The CVE names these as products and links their GitHub repository, and the package registry names the same repository, so they are probably the affected packages. Low confidence: the versions are the CVE’s own for the product, and a stack check reports the package as unchecked when there are none.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of amazon-braket/amazon-braket-schemas-python published their own advisory on GitHub. Reviewed sources take precedence over it.
