Executive Summary

A critical vulnerability, CVE-2026-32613, has been identified in the Maven package io.spinnaker.echo:echo-pipelinetriggers. This vulnerability allows attackers full access to the Java Virtual Machine (JVM), enabling them to execute arbitrary commands and access sensitive files. Solo developers and small teams are urged to take immediate action to mitigate potential risks.

Immediate Action

  • Disable the Echo service entirely until a fix is implemented.
  • Monitor for updates from Spinnaker regarding patched versions.
  • Consider isolating affected services in a separate environment.
  • Review your codebase for any dependencies on io.spinnaker.echo:echo-pipelinetriggers.
  • Stay informed through vendor advisories: Spinnaker Advisory

Affected Versions

  • io.spinnaker.echo:echo-pipelinetriggers@<=1.0.0 vulnerable
  • io.spinnaker.echo:echo-pipelinetriggers@1.0.1 vulnerable
  • Upgrade to 1.0.2 or later (confirm availability).

Resolution Guide

To mitigate the risk associated with this vulnerability:

mvn versions:use-latest-releases -Dincludes=io.spinnaker.echo:echo-pipelinetriggers

To disable the Echo service, you can modify your configuration settings. Example:

spring:
  echo:
    enabled: false

For a code fix, if applicable, ensure that your implementation restricts SPeL access to trusted classes only. Example snippet:

import org.springframework.expression.spel.support.StandardEvaluationContext;

StandardEvaluationContext context = new StandardEvaluationContext();
context.setRootObject(new TrustedObject()); // Ensure only trusted objects are accessible

Detection & Verification

To check if your application is vulnerable, run the following command:

mvn dependency:tree | grep echo-pipelinetriggers

Verify that you are using a safe version by checking the output. To confirm that the fix has been applied, use:

mvn dependency:tree | grep echo-pipelinetriggers

Ensure that the version displayed is 1.0.2 or higher.

Risk and Impact

If exploited, CVE-2026-32613 allows attackers to execute arbitrary commands on the JVM, potentially leading to complete system compromise. The blast radius includes any systems relying on the vulnerable Echo service, making it critical for developers to act swiftly to protect their applications and data.
