vite-plugin-crypto@1.0.0

vite-plugin-crypto@1.0.2 exposes a Vite plugin factory whose body concatenates three option fields — `secret`, `salt`, and `iv` — into a single string and passes it to `System.import(...)` from the `systemjs` runtime module loader, discarding the returned promise with `.then(() => {})`. Only `secret` is used by the advertised AES-GCM `encrypt()` path; `salt` and `iv` are declared on the options type but are absent from the documented options table and are unused by the real crypto code (which generates its own random salt/IV per call). The concatenated string is treated as a module specifier by SystemJS, which resolves URLs and executes fetched JavaScript, so whoever controls these option values obtains arbitrary JavaScript execution on the Vite build/dev host each time the config is loaded. Pulling in a browser-oriented dynamic module loader as the package's only runtime dependency, naming the concatenated input `derivedSecret`, and swallowing the promise frame the remote-loader call as a benign key-derivation step. Base64 decoding in dist/index.cjs and dist/index.js is used within the AES-GCM helper. The trigger fires at plugin construction during `vite build` / `vite dev`. ## Source: ghsa-malware (fdaf333e613f70df12ceaf378093d996a4bc1dd4df1a6350c4848a5de0fb83e7) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
