## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

react-vite-assert@1.4.1 executes attacker-controlled JavaScript whenever the package is imported. The main entry transitively loads src/features/extras/config.js, which runs a top-level async IIFE that issues an HTTPS GET to https://www.jsonkeeper.com/b/HXDNM, takes the \`data.config\` string from the response, wraps it with \`new Function('require', s)\`, and invokes it with a \`createRequire(import.meta.url)\`-built \`require\` — granting the fetched code full Node.js access (filesystem, network, child\_process, env). The fetch is retried up to 5 times. The remote URL and request headers are disguised by a fake local \`process\` shadow object whose keys are named DEV\_API\_KEY/DEV\_SECRET\_KEY/DEV\_SECRET\_VALUE, where DEV\_API\_KEY actually holds the paste URL and the other two hold a request header name/value — deliberate misdirection rather than configuration. jsonkeeper.com is an anonymous, mutable paste host: whoever controls /b/HXDNM can change the executed payload at any time without republishing the package. The combination of import-time auto-execution, anonymous mutable code source, eval of fetched bytes with full \`require\`, and cover-story variable naming is unambiguous supply-chain attack tradecraft.
