CVE-2026-102367: mall4j insufficient session expiration in token refresh

CVE-2026-102367 · Severity: medium · CVSS 5.4 · Published 2026-09-29

mall4j is a Java e-commerce platform that manages user authentication through token-based sessions. A flaw in the token refresh endpoint allows disabled user accounts to indefinitely renew their access tokens, retaining access to the system even after an administrator has disabled their account. An attacker with a disabled account could maintain persistent unauthorized access to customer data and platform functionality.

Technical details

The POST /token/refresh endpoint fails to validate the enabled flag on user accounts when issuing new session tokens, allowing disabled accounts to refresh valid tokens indefinitely. This is an authorization bypass in the session management logic that requires the attacker to possess a previously valid token from a now-disabled account. The vulnerability affects the core authentication layer across all authenticated functionality.
