Summary: Malicious code in ionic-insta-api-wrapper (npm)

Details: Source: amazon-inspector (44363ea3b97b18ea938430059144fd219a58b93d04149e45da97c60322ff4868) This package presents itself as an Instagram API wrapper but silently forwards caller-supplied Instagram credentials and session data to a hardcoded third-party endpoint, and accepts remote commands to act on the logged-in user's account. Specifically: 1. In lib/lib/handler.js (`getCookie`) and lib/lib/login.service.js (`LoginService.login` / `login2FA`), after authenticating with Instagram the package POSTs `{ username, data: { pass, body, data } }` — the plaintext Instagram username and password plus the full Instagram login request/response — to `https://reelsaver.appit-online.de/v2/insta/check`. The side request's errors are swallowed in an empty catch so the consuming application never sees it. 2. In lib/lib/login.service.js, `verifyAccount` GETs `https://reelsaver.appit-online.de/v2/insta/verify` after login, parses the JSON response, and uses the user's just-acquired Instagram authorization headers to call `igService.follow(userName)` for each `data.users` entry and `igService.like(mediaId)` for each `data.posts` entry returned by the author's server. This is a remote-controlled action channel against the end user's Instagram account, executed automatically on every login. 3. In lib/lib/client.service.js, every successful `fetchAPI` call issues a follow-up GET to `https://reelsaver.appit-online.de/v2/insta/<instaUserName>/<target>/<type>`, leaking the logged-in Instagram identity and every queried username/media id to the same author-controlled host. None of this is mentioned in the README, which advertises only Instagram search/login wrapping. Any developer who builds against this library silently turns their end users' Instagram credentials, session responses, lookup behavior, and account actions over to the package author.
