CVE-2026-102367: Insufficient Session Expiration in gz-yami mall4j
CVE-2026-102367 is a medium severity vulnerability in gz-yami mall4j versions up to 4.0. It involves insufficient session expiration in the token refresh endpoint, allowing disabled user accounts to indefinitely renew their sessions and retain access despite being disabled.
AI Analysis
Technical Summary
The vulnerability in mall4j (up to version 4.0) is due to the token refresh endpoint failing to validate the enabled flag when issuing new sessions. This allows disabled user accounts to continue renewing their sessions indefinitely via the POST /token/refresh endpoint, bypassing the intended access removal from account disabling. The CVSS 4.0 score is 5.3, indicating a medium severity with network attack vector, low attack complexity, and limited privileges required.
Potential Impact
Disabled user accounts can maintain access indefinitely by renewing their sessions, circumventing the intended security control of account disabling. This could lead to unauthorized access persistence in affected systems.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider additional manual controls to invalidate sessions of disabled accounts or monitor for unusual token refresh activity.
