Spinnaker is an open source, multi-cloud continuous delivery platform. Echo like some other services, uses SPeL (Spring Expression Language) to process information - specifically around expected artifacts. In versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, unlike orca, it was NOT restricting that context to a set of trusted classes, but allowing FULL JVM access. This enabled a user to use arbitrary java classes which allow deep access to the system. This enabled the ability to invoke commands, access files, etc. Versions 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2 contain a patch. As a workaround, disable echo entirely.
AnalysisAI
Remote code execution in Spinnaker's Echo service (all versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2) allows authenticated attackers with low privileges to execute arbitrary system commands and access files through unrestricted Spring Expression Language (SPeL) injection in artifact processing. Unlike Spinnaker's Orca service which implemented SPeL sandbox restrictions, Echo permits full JVM class access, enabling attackers to invoke arbitrary Java classes for deep system compromise. …

RemediationAI
Within 24 hours: Identify all Spinnaker Echo service instances and document current versions via spinnaker-diag or deployment manifests; isolate affected deployments from production pipelines if running versions prior to 2026.1.0, 2026.0.1, 2025.4.2, or 2025.3.2. Within 7 days: Apply vendor patches - upgrade to Echo 2026.1.0, 2026.0.1, 2025.4.2, or 2025.3.2 depending on your release track; validate patches via deployment testing in non-production environment. …
