CVE-2026-53455: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in ha-china blueprint-studio
CVE-2026-53455 is an OS command injection vulnerability in ha-china's Blueprint Studio, a VS Code-like editor for Home Assistant configuration files. Versions prior to 2.5.2 generate a shell-based Git credential helper by directly embedding user-configured Git usernames and tokens without validation. This allows an attacker who can set Git credentials to inject shell commands via special characters in the username or token. When Git runs the helper, the injected commands execute with Home Assistant's OS privileges, potentially accessing or modifying configuration data. The issue is fixed in version 2.5.2.
AI Analysis
Technical Summary
Blueprint Studio versions before 2.5.2 create a shell-based Git credential helper script by interpolating Git username and token values directly into executable script content without sanitization. This improper neutralization of special elements (CWE-78) enables an attacker who can control Git credentials to inject arbitrary shell commands. These commands execute with the operating system privileges of the Home Assistant process, risking unauthorized access or modification of Home Assistant configuration data. The vulnerability is resolved in version 2.5.2.
Potential Impact
An attacker able to set Git credentials can execute arbitrary OS commands with the privileges of the Home Assistant process. This can lead to unauthorized access or modification of Home Assistant configuration files, potentially compromising the system's integrity and security.
Mitigation Recommendations
Upgrade Blueprint Studio to version 2.5.2 or later, where this vulnerability is fixed by properly sanitizing Git credential inputs before generating the shell-based Git credential helper script.
