CVE-2026-107361 Authentication Bypass Using an Alternate Path or Channel in Malcolm

The Arkime live capture service arkime-live in Malcolm runs with networkmode: 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...

CVE-2026-107361

The Malcolm security tool is vulnerable to an authentication bypass in the Arkime live capture service (arkime-live) .

CVE-2026-19670

Malcolm's nginx Lua role-based access control RBAC layer decides whether an authenticated user may reach a role-restricted path e.g. /htadmin, /auth, /adminlogin, /arkime/api/esadmin, NetBox, upload endpoints by pattern-matching the raw, percent-encoded request URI. Nginx itself, however, selects...
