> DESCRIPTION

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.

CWE-470 CWE-502

> CWE DETAILED DESCRIPTIONS

CWE-470: Use of Externally-Controlled Input to Select Classes or Code - The product uses external input with reflection to select which classes or code to use, but it does not sufficiently prevent the input from selecting improper classes or code. | CWE-502: Deserialization of Untrusted Data - The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
