VulniPulse record published Record updated
Summary
launch-editor allows users to open files with line numbers in editor from Node.js. Prior to 2.14.1, the launch-editor NPM package accesses arbitrary paths including Windows UNC paths.
When a UNC path is opened, Windows automatically attempts NTLM authentication to the remote host, causing the user’s NTLMv2 password hash to be leaked to an attacker-controlled SMB server. This can result in credential compromise through offline hash cracking.
This vulnerability is fixed in 2.14.1. This component, used in Node.js to open files, can be tricked into accessing arbitrary paths, including Windows Universal Naming Convention (UNC) paths.
Red Hat rates this issue as having Moderate impact for Red Hat OpenShift AI MLflow images on Windows client scenarios. Linux-based Red Hat Enterprise Linux AI bootc images are not affected because launch-editor UNC-path behavior is Windows-specific.
Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N). Weakness: CWE-73.
Affected Red Hat products: Red Hat OpenShift AI (RHOAI).
