## Overview

Nagios Log Server versions prior to 2024R1.3.2 contain a privilege escalation vulnerability in the account email-change workflow. A user could set their own email to an invalid value and, due to insufficient validation and authorization checks tied to email identity state, trigger inconsistent account state that granted elevated privileges or bypassed intended access controls.

## Affected

- `log_server < 2024`
- `log_server = 2024`

## Remediation

Upgrade past the affected range:

- `log_server 2024`
