brioche-apl-dev-env

Details

**Severity:** Critical

**Affected versions:** `> 0`

brioche-apl-dev-env is a dependency-confusion package: it takes a name that looks like an internal project, uses an inflated version (100.0.0) so it outranks private-registry versions, and runs `node setup.js || true` as a preinstall script on npm install. setup.js sends the hostname, username, working directory, OS, architecture, Node.js version and configured npm registry, with a per-package tracking token, in an HTTPS POST to `https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook`. The npm account amel10 published brioche-apl-dev-env and 9 similar packages within two minutes on 2026-09-30, all with the same setup.js.
