How to Fix CVE-2026-11572

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

degit fixed: 2.8.6 
npm install degit@2.8.6
degit fixed: 3.3.1 
npm install degit@3.3.1
Verify Direct and Transitive Dependencies

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

npm ls degit

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-11572, inspect your project dependencies using npm:

npm ls degit

Analyze the terminal output to locate any version of Degit in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.8.6), your application is affected.

Note: The npm ls degit command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Degit, 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

Versions of the package degit before 2.8.6, from 3.0.0 and before 3.3.1 are vulnerable to Command Injection due to improper sanitisation of user input for git shell commands directly invoked with exec() method by _cloneWithGit() and fetchRefs() functions. An attacker can execute arbitrary operating system commands as the process user by supplying a specially crafted git repository name.
