Vulnerability MAL-2026-18452

sol-wallet-adapter takes the unscoped name of @project-serum/sol-wallet-adapter and has no functional code. Its preinstall script runs node preinstall.js on npm install, which POSTs the machine's hostname, the OS username and the local time to the Discord webhook https://canary.discord.com/api/webhooks/1566232728179843243/pM5rDIrCRrEpQRbA7ibaiQk1XOQlIftmBacA5s8jD8NvXn5W-rS832DOWHQS-G-j3N6U as "PC Notifier". Versions 1.0.0 and 1.0.1 were published on 2026-11-01 by the npm account cutekitten05; after they were removed, the account bigdevin55 re-created the name and published 1.0.7 with the same script on 2026-11-02, alongside contracts-upgradeable.
