CVE-2026-107361

Authentication Bypass Using an Alternate Path or Channel in Malcolm

Published Oct 8, 2026 CVSS 3.1 · 4.2 Medium EPSS < 1% KEV · Not listed
Description
The Arkime live capture service (arkime-live) in Malcolm runs with network_mode: host, exposing port 8005 on all network interfaces (viewHost=0.0.0.0). Arkime trusts the X-Forwarded-User header from any IP address (userAuthIps=::,0.0.0.0/0) and auto-creates users with full access. The passwordSecret is hardcoded to the public value "Malcolm". A network-adjacent attacker bypasses nginx entirely by connecting directly to port 8005 with a forged identity header.
