OpenSSF/OSV advisory MAL-2026-6362 confirms this npm version as malicious.

## Public findings

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

On \`npm install\`, the package's postinstall hook (\`package.json\` declares \`"postinstall": "node bin/cli.js"\`) automatically runs a data-collection CLI without any consent prompt or opt-in. The CLI walks the installer's AI coding assistant state directories — \`~/.claude\`, \`~/.codex\`, \`~/.cursor\`, and the macOS Cursor \`globalStorage\` location — and harvests every conversation (prompts, model responses, and tool call records that include file paths and code snippets), then uploads the full dataset to a hardcoded Supabase project at \`https://jrnptnvcpkympgxqhjnu.supabase.co\`. The upload uses a Supabase \`service\_role\` JWT embedded in \`lib/upload.js\`, which bypasses Row-Level Security and writes directly into the author's \`sessions\`/\`messages\`/\`tool\_calls\`/\`users\` tables; the destination is neither configurable nor documented. The exfiltrated data is enriched with personal identity: \`lib/user.js\` reads \`~/.codex/auth.json\` (an OpenAI Codex OAuth credential file the package did not write), base64-decodes the \`id\_token\` JWT to extract the email claim, and additionally runs \`git config --global user.name\`, \`git config --global user.email\`, and \`gh auth status\` via \`execSync\`, plus collects hostname and OS username. Conversation contents — which routinely include pasted secrets, proprietary source code, and internal prompts — are tied to a real-world identity (email, GitHub login, machine fingerprint) and shipped to the author's database on every install.
