Versa recommends disabling the Node.js web service on VOS devices after the initial provisioning is complete. This action effectively mitigates the vulnerability. There is no indication of an official patch or update; the mitigation relies on disabling the vulnerable service. Users should follow the Versa security hardening guide to disable this service post-provisioning.

Description

CVE-2026-107242 is a vulnerability in Versa VOS where the Node.js web service used for Zero Touch Provisioning (ZTP) generates session identifiers using UUID version 1. These UUIDs are predictable because they are based on system date, time, and MAC address, allowing an attacker to potentially hijack user sessions. The Node.js web service is not required after provisioning and can be disabled to mitigate this issue. Devices with this service disabled are not vulnerable.
