  1. CVE-2026-14227 4.9 Moyenne

    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.

  2. CVE-2026-16347 8.8 Élevée

    MikroTik RouterOS · MikroTik Cloud Hosted Router

    MikroTik RouterOS contains a weakness in its API authentication handling that lacks effective safeguards against excessive login attempts. The system does not enforce meaningful rate-limiting, account lockout, or source-based restrictions, allowing repeated authentication failures to proceed without defensive response. In some versions, a fixed per-connection delay is present, but it can be bypassed through concurrent sessions, resulting in continued high-volume attempts. This deficiency increases the risk that an attacker could eventually obtain valid credentials and gain unauthorized access to administrative services.

  3. CVE-2026-39042 7.5 Élevée

    An issue in MikroTIk (SIA Mikrotikls, Latvia) RouterOS 7.21.x before v.7.21.4 and 7.22.x before v.7.22.2 allows a remote attacker to cause a denial of service via the unflatten() function in libumsg.so.
