CVE-2026-32290

Estado: AnalizadaAlta (7)—

The GL-iNet Comet (GL-RM1) KVM before version 1.8.2 does not sufficiently verify the authenticity of uploaded firmware files. An attacker-in-the-middle or a compromised update server could modify the firmware and the corresponding MD5 hash to pass verification.

CVSS
