react-jsonwebtoken @9.0.5

Summary

Package name mimics the widely-used 'jsonwebtoken' library and falsely declares 'auth0' as author, while the repository URL points to the unrelated 'github.com/radix-ui/primitives'. On require(), decode.js unconditionally invokes a helper (getThirdCookie) that performs an HTTPS GET to https://jsonkeeper.com/b/E69V3 — an anonymous, mutable paste endpoint — and passes the response body into new Function.constructor("require", errCode) , then executes the resulting function with the host's require. This grants the remote content full Node.js capabilities on the consumer's machine as soon as any code loads the module. The code path is hidden behind a benign-sounding helper name and uses indirect Function construction to evade simple pattern matching. The combination of impersonated author metadata, name confusion with a top-100 auth library, and an obfuscated require-time remote-code loader is an unambiguous supply-chain attack.
