## Overview

mall4j through 4.0 contains an insufficient session expiration vulnerability in the token refresh endpoint that fails to validate the enabled flag when issuing new sessions. Disabled user accounts can indefinitely renew their sessions through the POST /token/refresh endpoint, retaining access that account disabling was intended to remove.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
