• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days

• Published: 2026-04-20 · updated 2026-06-17

Description

Spinnaker is an open source, multi-cloud continuous delivery platform. In versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, a bad actor can execute arbitrary commands very simply on the clouddriver pods. This can expose credentials, remove files, or inject resources easily. Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 contain a patch. As a workaround, disable the gitrepo artifact types.

Affected products

• spinnaker: before 2025.3.2; from 2025.4.0 before 2025.4.2; from 2026.0.0 before 2026.0.1 — fixed in 2025.3.2, 2025.4.2, 2026.0.1

How to fix

Upgrade to a fixed version: spinnaker 2025.3.2, 2025.4.2, 2026.0.1. Check the vendor advisory for mitigations.
