Description

This security bulletin contains information about 1 vulnerability.


1) Deserialization of Untrusted Data (CVE-ID: CVE-2026-9291)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: 7.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to execute arbitrary code.

The vulnerability exists due to deserialization of untrusted data in the deserialize_values() function when processing job results JSON files. A remote user can modify the dataFormat field and supply base64-encoded serialized payloads to execute arbitrary code.

Exploitation requires S3 write access to a Braket job output bucket and user interaction when the victim calls job.result(), load_job_result(), or load_job_checkpoint().
