概要

Impact

There's an unsafe YAML processing vulnerability that bypasses safe deserialization. This impacts users when when performing:

CloudFormation deployments
CloudFoundry Baking

The usage of a non-safe constructor use allows arbitrary loading of Java classes leading to RCE.

Patches

2025.3.3, 2026.0.3 and 2025.4.4.

Workarounds

Disable the CloudFormation system and cloudfoundry baking operations.

NVD の説明

Spinnaker is an open source, multi-cloud continuous delivery platform. Prior to 2026.1.0, 2026.0.3, 2025.4.4, and 2025.3.3, unsafe YAML processing bypasses safe deserialization when using CloudFormation deployments or CloudFoundry baking. The use of a non-safe constructor allows arbitrary loading of Java classes, leading to remote code execution. This issue is fixed in versions 2026.1.0, 2026.0.3, 2025.4.4, and 2025.3.3.
