Summary

SAP yeoman-ui, the package behind the Yeoman-UI extension for VS Code, is affected from ?1.25.1. Generator installation and uninstallation pass the ApplicationWizard.installationLocation workspace setting to a shell string without sanitisation, an OS command injection flaw (CWE-78). A malicious workspace repository can run OS commands with the developer's privileges when the developer opens the project and triggers a generator installation.

Description from the CNA

The affected code used child_process.execSync with a shell string for generator installation and uninstallation. This allowed an attacker to execute arbitrary OS commands with the developer's privileges by manipulating the ApplicationWizard.installationLocation VS Code workspace configuration value. Because the value was passed directly to the shell without sanitisation, a malicious workspace repository could craft a settings.json that injects OS commands when a developer opens the project and triggers a generator installation.
