PYSEC-2026-1889
sagemaker-python-sdk vulnerable to Deserialization of Untrusted Data
Quick fix
PYSEC-2026-1889 — sagemaker: upgrade to the fixed version with the command below.
pip install --upgrade 'sagemaker>=2.218.0'Details
### Impact
sagemaker.base_deserializers.NumpyDeserializer module before v2.218.0 allows potentially unsafe deserialization when untrusted data is passed as pickled object arrays. This consequently may allow an unprivileged third party to cause remote code execution, denial of service, affecting both confidentiality and integrity.
Impacted versions: <2.218.0.
### Credit
We would like to thank HiddenLayer for collaborating on this issue through the coordinated vulnerability disclosure process.
### Workarounds
Do not pass pickled numpy object arrays which originated from an untrusted source, or that could have been tampered with. Only pass pickled numpy object arrays from sources you trust.
