The module also deletes its own entries from require.cache so the payload re-runs on each require() rather than being memoized. The package name and the thunderbolt/editor/corvid Proxy facade impersonate Wix parastorage registry modules to encourage accidental installation.\n\n---\n\nCredit: OpenSSF (source)","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.387Z","source_updated_at":"2026-10-05T06:30:31.000Z","source_disclosed_at":"2026-10-05T06:30:29.000Z","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"}
