## Overview

A flaw was found in Moodle. User list filters do not properly enforce visibility restrictions on user profile fields. An authorized user with manager privileges can filter user lists using profile attributes they are not permitted to view directly, resulting in unauthorized information disclosure by inferring hidden user data.

## Affected

- `moodle < 4.5.13`
- `moodle >= 5.0.0, < 5.0.9`
- `moodle >= 5.1.0, < 5.1.6`
- `moodle >= 5.2.0, < 5.2.2`

## Remediation

Upgrade past the affected range:

- `moodle 5.2.2`
