CVE-2026-29771: Netmaker

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Netmaker makes networks with WireGuard. Prior to version 1.2.0, the /api/server/shutdown endpoint allows termination of the Netmaker server process via syscall.SIGINT. This allows any user to repeatedly shut down the server, causing cyclic denial of service with approximately 3-second restart intervals. This issue has been patched in version 1.2.0.
