CVE-2026-44795 Details
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.
A vulnerability in Spinnaker's YAML processing allows for unsafe deserialization, which can be exploited during CloudFormation deployments or CloudFoundry baking. Prior to versions 2026.1.0, 2026.0.3, 2025.4.4, and 2025.3.3, the use of a non-safe constructor in YAML processing permitted the arbitrary loading of Java classes. This flaw could be exploited to execute remote code, creating a significant security risk.
Users can update to Spinnaker versions 2026.1.0, 2026.0.3, 2025.4.4, or 2025.3.3 to address this vulnerability. If an immediate update is not possible, consider disabling CloudFormation and CloudFoundry baking operations until the update can be applied.
