# Chrome on iOS: crafted page can spoof Passwords dialog elements

A crafted HTML page can make fake interface elements appear in Passwords in Google Chrome on iOS, so a user may be tricked into social engineering actions. The sources rate the Chromium security severity as Medium and describe social engineering as a requirement.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Chrome version on the iPhone or iPad under Chrome > Settings > Google Chrome > About Chrome (unknown if the sources give this path; the version to compare is in the fix section).
- Compare the installed version against `157.0.8103.38`.

## Fix

- Google Chrome on iOS: move to `157.0.8103.38` or later.
