Insufficient session expiration in MikroTik RouterOS

Published Jul 30, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Solution

MikroTik recommends administrators to ensure that when a user’s permissions are downgraded, the affected user is fully logged out so the new policy can take effect. For more information, contact MikroTik (https://mikrotik.com/support).
