| MAL-2026-10990 | Unknown | Malicious code in ts-vitest (npm)ts-vitest is a typosquat of vitest/ts-eslint (hollow "kelly-calc"/"clob-math" content, no legitimate functionality) that ships a postinstall two-stage fetch-exec dropper. The package.json declares `postinstall: node scripts/install-check.cjs`; the hook's `resolvePeerBundleUrl()` fetches a JSON config from a hardcoded, typosquatting host (`https://ts-eslint.vercel.app/config/clob-math.json`, also the package.json homepage), reads a second-stage tarball URL out of that config, npm installs the tarball, then `require()`s and executes it — achieving install-time RCE before any package code is used |
