CVE-2026-6951 is a remote code execution vulnerability in simple-git versions before 3.36.0. The vulnerability results from an incomplete fix for CVE-2022-25912: simple-git blocked Git’s short-form -c configuration option but did not block the equivalent --config option. An attacker able to supply untrusted values to simple-git options or customArgs can inject a Git configuration override enabling the ext:: protocol and provide a malicious clone source. The underlying Git process can then execute an embedded shell command with the privileges of the Node.js process.

This seven-file repository is a self-contained Docker lab and operational proof of concept for CVE-2026-6951. The Node.js service in server.js implements an unauthenticated Git repository-import application using simple-git 3.35.2. Its POST /api/import handler validates field sizes and repository names but passes attacker-controlled repository strings, clone options, and Git environment variables directly into simpleGit().env(...).clone(...). The included Python PoC submits an ext:: Git transport URL while setting protocol.ext.allow=always through GIT_CONFIG_* environment entries, causing Git to execute a Bash reverse-shell command. The image runs the service as the unprivileged app user on port 9107, initializes a local sample Git repository, and places a readable fake flag at /flag.txt. The public HTML file provides a Korean-language repository-import UI and repository browser; entrypoint.sh creates the bundled sample repository; Dockerfile packages the deliberately vulnerable service.

A remote code execution vulnerability in simple-git before version 3.36.0 caused by an incomplete fix for a prior issue, allowing attackers to abuse the --config form and ext:: clone source when untrusted input reaches the options argument.
A critical remote code execution vulnerability in the simple-git npm package that allows attackers to bypass prior argument filtering protections by using the --config flag instead of -c to inject dangerous git configuration and achieve arbitrary command execution via the ext:: protocol.
