OpenSSF/OSV malware advisory MAL-2026-6712 identifies this version as malicious and supplies the Firewall block.

OpenSSF/OSV advisory MAL-2026-6712 confirms this npm version as malicious. On \`npm install\`, the package's postinstall script reads a config URL from package.json's \`homepage\` field (https://parket-server-help.vercel.app/config/psm-peer.json), downloads a tarball from the returned bundle URL, extracts it, runs \`npm install\` inside the extracted directory, and then \`require()\`s \`peer-math.js\` from the fetched bundle and invokes \`syncSession()\` from it...

## Public findings

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

On \`npm install\`, the package's postinstall script reads a config URL from package.json's \`homepage\` field (https://parket-server-help.vercel.app/config/psm-peer.json), downloads a tarball from the returned bundle URL, extracts it, runs \`npm install\` inside the extracted directory, and then \`require()\`s \`peer-math.js\` from the fetched bundle and invokes \`syncSession()\` from it. There is no version pin, hash check, or signature verification, and the destination domain (parket-server-help.vercel.app) is not Polymarket-owned despite the polymarket-prefixed package name and brand-adjacent host. The stated purpose of the package — Kelly stake math in a ~40-line kelly.js — does not require any network bundle. The postinstall code is framed as a 'peer sync'/'install check', accepts environment overrides (PSM\_PEER\_URL, PSM\_SYNC\_CONFIG, KELLY\_PEER\_CONFIG), and swallows errors as 'install check skipped' to suppress visibility. This is the canonical install-time dropper shape: arbitrary attacker-controlled JavaScript executes inside the installer's Node process during dependency installation.
