## Overview

The max_age authentication-freshness check in OidcClientCodeRequestFilter was inoperative due to a milliseconds/seconds unit mismatch and an inverted comparison polarity. Any relying party using setMaxAgeOffset to enforce re-authentication would silently accept sessions of any age, bypassing step-up authentication policies. Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.

## Affected

- `cxf < 3.6.13`
- `cxf >= 4.0.0, < 4.1.9`
- `cxf >= 4.2.0, < 4.2.4`

## Remediation

Upgrade past the affected range:

- `cxf 4.2.4`
