## Public findings

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

commonweb-flow@7.999.999 declares its sole dependency \`linker-event-header-serial\` as a direct tarball URL on \`artifacts.yosiroute.com\` (not the npm registry), and npm-shrinkwrap.json marks that dependency with \`hasInstallScript: true\`. On \`npm install\`, npm fetches the tarball from \`artifacts.yosiroute.com\` and runs its lifecycle install scripts, giving that host arbitrary code execution on the installer's machine. The tarball contents at that URL are mutable and can be swapped server-side without republishing commonweb-flow. Package metadata is placeholder (\`author: "Package Registry"\`, \`description: "Generated package"\`, repository \`github.com/example/commonweb-flow\`), and the manifest version \`7.999.999\` is inflated relative to the README/index.js self-reported \`1.0.0\` — the shape of a dependency-confusion lure aimed at internal builds that resolve \`commonweb-flow\` from the public registry over an internal package of the same name.
