Summary

CVE-2026-32295 is a critical-severity Improper Restriction of Excessive Authentication Attempts (CWE-307) vulnerability in Jetkvm Kvm. Its CVSS base score is 9.3 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 40th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-32295 affects JetKVM versions before 0.5.4, where the software fails to rate limit login requests. This design flaw enables brute-force attacks to guess credentials, as classified under CWE-307 (Improper Restriction of Excessive Authentication Attempts). The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), highlighting its high severity due to network accessibility and potential for significant confidentiality impact.

Attackers with network access to a vulnerable JetKVM instance can exploit this without prior privileges or user interaction. By sending repeated login attempts, they can systematically guess credentials, potentially compromising access to the device's KVM (keyboard, video, mouse) functionality and exposing sensitive remote control capabilities.

Mitigation involves upgrading to JetKVM version 0.5.4, available via the project's GitHub release page, which addresses the rate limiting deficiency. Advisories from Eclypsium, CISA (via CSAF document VA-26-076-01), and the official CVE record detail the issue and emphasize applying the patch promptly.

AC-7 Unsuccessful Logon Attempts good match

AC-7 directly enforces limits on consecutive failed logons, structurally blocking brute-force exploitation of the weakness.
