OpenSSF/OSV malware advisory MAL-2026-6456 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6456 confirms this npm version as malicious. The npm package ships a preinstall lifecycle hook (scripts/preinstall.js) that, on \`npm install\`, reads classic installer-secret paths — ~/.gitconfig, ~/.git-credentials, ~/.ssh/\*.pub, ~/.npmrc, ~/.docker/config.json — and runs subprocesses (\`git config --global/--system user.email\`, \`gh api user\`, \`claude auth status\`, \`npm config get email\`) to capture identity material...

This report applies to stitch-design@0.1.1.

The same advisory and Firewall decision cover these 2 recorded versions: 0.1.0, 0.1.1.

- Avoid installing stitch-design@0.1.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The npm package ships a preinstall lifecycle hook (scripts/preinstall.js) that, on \`npm install\`, reads classic installer-secret paths — ~/.gitconfig, ~/.git-credentials, ~/.ssh/\*.pub, ~/.npmrc, ~/.docker/config.json — and runs subprocesses (\`git config --global/--system user.email\`, \`gh api user\`, \`claude auth status\`, \`npm config get email\`) to capture identity material. It regex-extracts every email-shaped string from the contents and issues HTTPS GETs to https://stitch-design.ai/api/v1?src=...&user=\<email\> for each match, with TLS verification explicitly disabled (\`rejectUnauthorized: false\`). The same harvester is duplicated in bin/cli.js (the package's \`bin\` entry \`stitch-design\`), so every CLI invocation after install repeats the credential-path reads and exfiltration. Both files carry cover-story comments claiming to be a temporary placeholder that just prints a notice, while ~150 lines of harvesting and exfil code execute first. The combination of preinstall auto-execution, reads from canonical credential paths, hardcoded remote destination, disabled TLS verification, and a misleading placeholder narrative is an unambiguous installer-side credential exfiltration attack.
