Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The amazon-braket-sdk package, versions 1.10.0 up to but not including 1.117.0, is vulnerable to insecure deserialization. An attacker with write access to the S3 bucket that stores a Braket job's output can alter the results file so the SDK calls pickle.loads() on attacker-supplied data when the victim retrieves job results, allowing arbitrary code execution with the victim's permissions. Upgrade to amazon-braket-sdk 1.117.0 or later. As a workaround, restrict s3:PutObject permissions on job output buckets to trusted principals only.
