CVE-2026-32295Network attack vector

Password guessing via unlimited login attempts

Published Mar 17, 2026 · Updated Mar 17, 2026

Improper login-attempt restriction in BuildJet JetKVM before 0.5.4 allows remote attackers to guess the device password. The unauthenticated /auth/login-local path accepts unlimited password submissions because it neither tracks failures nor delays or locks out their source. Network access to the local web interface and a guessable configured password are required; a correct guess grants the KVM access assigned to that password.
