Deferred Deferred - Pending Action

Command Injection in Umi Framework

Publication date: 2026-07-22

Last updated on: 2026-07-22

Assigner: VulDB

Description
A weakness has been identified in umijs umi up to 4.6.63. The affected element is the function git.getFileCreateInfo of the file packages/utils/src/getFileGitIno.ts of the component GIT File Helper. This manipulation causes os command injection. The exploit has been made available to the public and could be used for attacks. Upgrading to version 4.6.64 is sufficient to fix this issue. Patch name: b6da12c17b024a43badb1fa565720c38cf42e647. Upgrading the affected component is advised.

Executive Summary

This vulnerability is a command injection flaw in the Umi.js framework up to version 4.6.63. It exists in the git.getFileCreateInfo function of the packages/utils/src/getFileGitIno.ts file. The issue allows attackers to execute arbitrary shell commands by manipulating file paths passed to git operations. The root cause is the use of shell: true in cross-spawn calls, which interprets user-controlled file paths as commands.

Detection Guidance

Check if your system uses umi versions up to 4.6.63 by running: npm list umi or yarn list umi. Inspect files in packages/utils/src/getFileGitIno.ts for shell: true usage in git helper functions. Look for unexpected file creation or command execution logs in system logs.

Impact Analysis

If you use affected versions of Umi.js (up to 4.6.63), an attacker could execute arbitrary commands on your system with the privileges of the Node.js process. This could lead to data theft, system compromise, or further network attacks. The vulnerability is particularly dangerous when processing untrusted file paths or git metadata from user-controlled sources.

Compliance Impact

This vulnerability could lead to unauthorized code execution, potentially violating data protection requirements under GDPR (Article 32 security of processing) and HIPAA (Security Rule integrity requirements). It may result in unauthorized access to personal data or protected health information, leading to compliance breaches and regulatory penalties.

Mitigation Strategies

Upgrade umi to version 4.6.64 or later using npm update umi or yarn upgrade umi. If upgrading is not possible, remove shell: true from git helper functions in getFileGitIno.ts and add -- before filePath arguments.
