How to Fix CVE-2026-32613

To remediate this vulnerability, upgrade all affected Spinnaker dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.spinnaker.echo:echo-pipelinetriggers fixed: 2026.0.1 
<dependency>
    <groupId>io.spinnaker.echo</groupId>
    <artifactId>echo-pipelinetriggers</artifactId>
    <version>2026.0.1</version>
</dependency>
io.spinnaker.echo:echo-pipelinetriggers fixed: 2025.4.2 
<dependency>
    <groupId>io.spinnaker.echo</groupId>
    <artifactId>echo-pipelinetriggers</artifactId>
    <version>2025.4.2</version>
</dependency>
io.spinnaker.echo:echo-pipelinetriggers fixed: 2025.3.2 
<dependency>
    <groupId>io.spinnaker.echo</groupId>
    <artifactId>echo-pipelinetriggers</artifactId>
    <version>2025.3.2</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.spinnaker.echo

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-32613, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.spinnaker.echo

Analyze the terminal output to locate any version of Spinnaker in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.0.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.spinnaker.echo command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Spinnaker, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
