Summary

Relative path traversal in the local hybrid job input data download in Amazon Braket SDK before 1.127.7 might allow a remote authenticated user with S3 write access to a hybrid job's input data location to overwrite arbitrary files with the privileges of the user running the job via crafted S3 object keys.

We recommend you upgrade to amazon-braket-sdk version 1.127.7 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-sdk-python published their own advisory on GitHub. Reviewed sources take precedence over it.
