Summary

CVE-2026-32613 is a critical-severity Code Injection (CWE-94) vulnerability in Linuxfoundation Spinnaker. Its CVSS base score is 9.9 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 43th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-32613 is a critical vulnerability in Spinnaker, an open-source multi-cloud continuous delivery platform, specifically affecting its Echo service. Echo uses Spring Expression Language (SpEL) to process information around expected artifacts without restricting the evaluation context to trusted classes—unlike the Orca service—allowing full JVM access. This enables attackers to invoke arbitrary Java classes for deep system access. The issue impacts versions prior to 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, with a CVSS v3.1 score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) and is classified under CWE-94 (code injection).

An authenticated attacker with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction. Successful exploitation grants arbitrary Java class usage, enabling remote code execution such as invoking system commands and accessing files, with high impacts across confidentiality, integrity, and availability due to the changed scope.

Patched versions include 2026.1.0, 2026.0.1, 2025.4.2, and 2025.3.2, as detailed in Spinnaker release notes and security advisory GHSA-69rw-45wj-g4v6. A recommended workaround is to disable the Echo service entirely.

A blog post on zeropath.com describes a production compromise involving Spinnaker RCE, suggesting real-world exploitation has occurred.

Vulnerability Data

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…

more

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.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.

none

Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
