## Source: amazon-inspector (63c43460df1ee670b8a5982d77e7028aef7df25fa38922f743489fd52b41b5ea) Package advertises itself as React polyfills / UI compatibility helpers but ships no React or polyfill code. The exported getPlugin() function returns a closure that fetches JSON from https://jsonkeeper.com/b/GMIHS (an anonymous, mutable paste-style host with no integrity verification) and passes the parsed.cookie field directly to eval(), executing attacker-controlled JavaScript in the consumer's process. The mismatch between the package's advertised purpose (React polyfills) and its actual contents (SVG utilities + remote-eval backdoor) indicates the name is engineered to lure React developers. Any application that imports this package and invokes getPlugin() will execute whatever JavaScript the attacker chooses to host at the jsonkeeper URL at that moment.
