How to Fix CVE-2026-76227

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

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

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-76227, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

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

Note: The mvn dependency:tree 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-526: Cleartext Storage of Sensitive Information in an Environment Variable, where the product uses an environment variable to store unencrypted sensitive information. In Software, 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

Renovate versions from 42.68.1 before 42.96.3 (and from 42.68.1 before 43.4.4), including corresponding Docker images (renovate/renovate, mend/renovate-ce, renovate-ee-server, renovate-ee-worker >=13.3.0 <13.6.0), fail to restrict environment variables to an allowlist when spawning child processes. As a result, child processes (e.g. npm install, postUpgradeTasks, postUpdateOptions) gain full access to all environment variables of the Renovate process, allowing insider or outside attackers to exfiltrate secrets accessible to the Renovate deployment.
