CVE-2026-44190 in Ansible Lightspeed Visual Studio Code Extension
Summary
by MITRE • 07/22/2026
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.

The vulnerability resides within the Ansible Lightspeed extension for Visual Studio Code, specifically targeting the `ansible.python.activationScript` configuration setting that is designed to facilitate virtual environment activation. This flaw represents a classic command injection vulnerability classified as CWE-78, which occurs when untrusted data is incorporated into system commands without proper sanitization or validation. The extension's failure to properly validate user-provided file paths creates an exploitable condition where attacker-controlled input can be interpreted as executable commands rather than benign file references.
The technical execution of this vulnerability depends on the extension's improper handling of the activation script parameter during project initialization or when processing user configurations. When a user opens or executes a maliciously crafted project, the extension processes the `ansible.python.activationScript` value without adequate input validation, allowing arbitrary command execution. This misconfiguration enables an attacker to inject malicious commands that will be executed within the context of the Visual Studio Code application's privileges, which typically operate with the same permissions as the user running the IDE.
The operational impact of this vulnerability is severe and potentially catastrophic for users who inadvertently open compromised projects or work in environments where such attacks could occur. An attacker exploiting this vulnerability gains complete system control with the privileges of the Visual Studio Code process, potentially allowing them to access sensitive configuration files, execute arbitrary code, modify project files, or even establish persistence mechanisms within the user's development environment. This attack vector specifically aligns with techniques described in the ATT&CK framework under execution and privilege escalation tactics, where adversaries leverage legitimate system tools to execute malicious payloads.
Organizations and individual developers should immediately disable or uninstall the affected Ansible Lightspeed extension until a patched version is available from the vendor. Users should avoid opening projects from untrusted sources and implement strict input validation practices when configuring IDE extensions. Security monitoring should include detection of suspicious command execution patterns within development environments, particularly when dealing with configuration files that may contain system command invocations. The vulnerability highlights the critical importance of proper input sanitization in development tools and emphasizes the need for secure coding practices that prevent command injection flaws in applications handling user-provided data through configuration parameters.
