CVE-2026-102829

CriticalCVSS 9.2
Published: Translated: NVD NIST

Summary

simple-git, an interface for running git commands in any node.js application, enables applications to execute Git operations from JavaScript. Prior to 2.0.1 of the argv-parser package, parseEnv omits VISUAL from GitEnvKeys, so prepareEnv drops the value before vulnerabilityCheck can classify it as allowUnsafeEditor. A consuming application that forwards attacker-influenced environment values can therefore allow Git to invoke an attacker-selected editor during operations such as commit amendment or interactive rebase when no higher-priority editor setting overrides VISUAL and Git's terminal prerequisites are met. The executable runs with the privileges of the Node.js process. This issue is fixed in argv-parser 2.0.1.

Risk Assessment

An attacker could influence the application's runtime environment to execute an arbitrary editor, potentially leading to arbitrary code execution with Node.js process privileges.

Recommendation

Update the argv-parser package to version 2.0.1 or later to prevent the omission of the VISUAL variable.
