          "text": "The Genesys demo page \u2014 deployed publicly at `https://ssagov.github.io/genesys/demo/genesys-demo.html` and linked from the repository README \u2014 loads executable JavaScript from `cdn.polyfill.io`, a domain that was **sold to Funnull Technology Inc. in February 2024** and **served malicious payloads** (device-fingerprinted redirects to sports-betting and scam sites via `googie-anaiytics.com`) **in June 2024**. Google suspended Ads for embedding sites, Namecheap suspended the domain, Cloudflare and Fastly stood up safe mirrors, and the hostname is on Google Safe Browsing and uBlock Origin blocklists. Ownership of the domain remains with the hostile party.\n\nThe vendored Mavo v0.2.0 bundle \u2014 the library behind the toolkit\u0027s data-persistence feature (the release notes record \"Added Data Persistence (Mavo)\" at `docs/Release-Notes.md:179`, and the demo template loads the bundle at `demo/genesys-demo.html:36`) \u2014 contains a second, runtime reference: when browser feature-detection finds any missing capability, Mavo dynamically injects a `\u003cscript\u003e` for `https://cdn.polyfill.io/v2/polyfill.min.js?unknown=polyfill\u0026features=\u2026`. This propagates the compromised reference into downstream prototypes built from the toolkit, which the README describes as ranging up to production-ready user interfaces.\n\nThe `ssagov.github.io` origin carries no session, authentication, or user data, which bounds CVSS impact at `L/L/L`. The finding is rated High rather than the Medium normally assigned to no-SRI CDN loads because the third party is not a trusted CDN operator who might be compromised \u2014 **it is a hostile-owned domain that has already served malware from this exact URL**. SRI would not mitigate (the domain owner controls the response); removal is the only fix.",
