The package exports factories under names matching Wix internal registry modules (thunderboltRegistry, corvidRegistry, siteAssetsRegistry, editorRegistry, documentManagementRegistry) and ships a manifest referencing parastorage.com URLs, so any environment loading it as a drop-in Wix thunderbolt registry triggers the exfiltration payload on require(). The declared CSS @starting-style polyfill purpose has no relationship to the shipped behavior.\n\n---\n\nCredit: OpenSSF (source)","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.409Z","source_updated_at":"2026-10-05T00:30:48.000Z","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":"42594"}
