ArcSearch for iOS versions prior to 1.48.0 could keep the address bar hidden after a page-initiated scroll, allowing attacker-controlled content to imitate browser interface elements and increasing spoofing risk.

## What to do

- Check your stack: if you ship or depend on The Browser Company of New York ArcSearch, upgrade to a fixed version (1.48.0) per the references below.
