GCVE-110-OSM-2026-13390

The package shadows internal Wix registry module names (thunderboltRegistry, corvidRegistry, editorRegistry, siteAssetsRegistry, and others) and ships a registry-manifest.min.json pointing at a parastorage CDN URL so that loading one of these registry entries resolves to this package's code. thunderboltRegistry.js runs an IIFE at module load that executes `id` and `hostname` via child_process.execSync, combines the output with process.platform, process.arch, process.pid, and process.version, and sends the values as query-string parameters in a fetch() call to the hardcoded collector https://webhook.site/43022177-de67-4d5c-a6df-33083b2b026f. The exported factories return Proxy stubs rather than implementing the real registry contracts, so the module's only effective behavior when loaded by a Wix SSR host is the reconnaissance beacon.
