CVE-2026-44190

Summary

A flaw was found in the Ansible Lightspeed Visual Studio Code extension. This Command Injection vulnerability (CWE-78) allows a remote attacker to execute unauthorized commands on a user's system. The issue occurs because the ansible.python.activationScript setting, intended for a virtual environment activation script, does not properly validate user input as a file path. If a user opens or executes a specially crafted project, an attacker could exploit this to gain complete control over the user's system with the privileges of the Visual Studio Code application.

Affected Software

Weaknesses

• CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Workarounds

To mitigate this issue, configure the ansible.python.activationScript setting to "User" scope only within Visual Studio Code settings. This prevents untrusted project configurations from defining this setting in .vscode/settings.json. Users should always review the contents of .vscode/settings.json before opening or executing playbooks from untrusted sources. This action does not require a service restart or reload.
