A fix is available — apply it.

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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
