CVE-2026-110631

Summary

Komodo's Periphery agent has a critical authentication bypass flaw where empty core public keys and passkeys lists cause the system to accept any keypair, allowing unauthenticated attackers to impersonate trusted Core components and execute commands as root on managed hosts.

Exploitability

Very easy to exploit with no prerequisites - attackers only need to reach port 8120 and present any generated keypair to gain full Periphery API access including terminal sessions and container operations.

Blast radius

High impact across all managed hosts that are accessible through the vulnerable Periphery agent, potentially allowing complete compromise of the entire infrastructure as root privileges are typically used for container operations and system commands.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to Komodo 2.3.4 or later to fix the authentication bypass vulnerability in the Periphery agent.
