Vulnerability Title
Spinnaker: Non-safe yaml deserialization allowing RCE when using specific types
Source: NVD (National Vulnerability Database)
Vulnerability 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.

Vulnerability Title
Spinnaker 代码注入漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Spinnaker是Spinnaker团队开源的一个持续交付平台。用于以高速度和高信心发布软件更改。 Spinnaker存在安全漏洞，该漏洞源于当使用CloudFormation部署或CloudFoundry烘焙时，不安全的YAML处理会绕过安全的反序列化，使用非安全的构造函数允许任意加载Java类，导致远程代码执行。以下版本受到影响：2026.1.0之前版本、2026.0.3之前版本、2025.4.4之前版本和2025.3.3之前版本。
