Malicious code in colossal_wallaby_pink-87 (npm)

Details

**Severity:** Critical

**Affected versions:** `= 1.2.1`

Part of a self-republishing campaign: generated names of the form <adjective>_<animal>_<colour>-<number>, each package shipping the same autopublish.js, which runs `npm publish --access public` to publish the package again. Self-replicating publication is the propagation step of a registry worm and fills the registry with copies. Version examined: 1.2.1; tarball SHA-256 eefa5998b053240ecd251b218193b2352c7dc55759fcaaeeb814f3c5fccf9539.
