Status: published. Published: 2026-11-09. Updated: 2026-11-09.

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.
