CVE-2026-14227: CWE-613 Insufficient session expiration in MikroTik RouterOS
An API session‑management flaw in products with the MikroTik RouterOS API enabled are vulnerable to a Insufficient Session Expiration vulnerability. This could allow active sessions to retain their previous permission set after inactivity timeouts or user‑group changes. As a result, an authenticated user whose permissions have been reduced may continue accessing information.
AI Analysis
Technical Summary
CVE-2026-14227 describes an insufficient session expiration vulnerability in MikroTik RouterOS API session management. The flaw allows active API sessions to maintain their prior permission sets despite inactivity timeouts or modifications to user-group permissions. Consequently, authenticated users whose privileges have been downgraded may still access resources at their previous permission level, potentially exposing sensitive information. The vulnerability is identified as CWE-613 (Insufficient Session Expiration). No official remediation or patch has been confirmed at this time.
Potential Impact
An authenticated user with reduced permissions may continue to access information or perform actions allowed by their previous higher permission set due to sessions not expiring or updating correctly. This could lead to unauthorized access to sensitive data or functionality within MikroTik RouterOS environments where the API is enabled.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should consider manually terminating active API sessions when user permissions change or after inactivity timeouts to reduce risk.
