CVE-2026-53632

Description

A flaw was found in launch-editor. This component, used in Node.js to open files, can be tricked into accessing arbitrary paths, including Windows Universal Naming Convention (UNC) paths. When a malicious UNC path is opened, Windows automatically attempts NTLM authentication to a remote server controlled by an attacker. This action leaks the user's NTLMv2 password hash, which can then be used by an attacker to compromise user credentials through offline cracking.

Statement

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.

Mitigation

Avoid using launch-editor on Windows clients against untrusted URLs. Upgrade when updated packages are available.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)

Integrity,Confidentiality

Technical Impact: Read Files or Directories; Modify Files or Directories

The application can operate on unexpected files. Confidentiality is violated when the targeted filename is not directly readable by the attacker.

Integrity,Confidentiality,Availability

Technical Impact: Modify Files or Directories; Execute Unauthorized Code or Commands

The application can operate on unexpected files. This may violate integrity if the filename is written to, or if the filename is for a program or other form of executable code.

Availability

Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (Other)

The application can operate on unexpected files. Availability can be violated if the attacker specifies an unexpected file that the application modifies. Availability can also be affected if the attacker specifies a filename for a large file, or points to a special device or a file that does not have the format that the application expects.
