## Affected

- Unknown User Access Manager: fixed in 2.2.18

The User Access Manager WordPress plugin before 2.2.18 prioritizes getting a visitor's IP from certain HTTP headers over PHP's REMOTE_ADDR, which makes it possible for attackers to access restricted content in certain situations.

## What to do
