The loader deletes any require.cache entry containing 'thunderboltRegistry' so the IIFE re-fires on subsequent requires, and falls back to node:child_process and new module.constructor().require('child_process') to obtain the exec primitive. The package also exports stubs named thunderboltRegistry, siteAssetsRegistry, documentManagementRegistry, editorRegistry, corvidRegistry and similar, matching internal Wix thunderbolt module names, with a registry-manifest.min.json pointing at static.parastorage.com unpkg paths — a dependency-confusion shape targeting an internal namespace. The declared CSS-utility purpose is unrelated to any of this behavior.\n\n---\n\nCredit: [OpenSSF](https://github.com/ossf/malic","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.389Z","source_updated_at":"2026-10-05T00:30:47.000Z","source_disclosed_at":"2026-10-05T00:30:39.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T23:13:05.881Z"}],"next_cursor":null,"snapshot_revision":"39771"}
