CVE-2026-104854
Description
A flaw was found in Nx. The application creates communication endpoints (Unix domain sockets) for its background service and worker processes in shared temporary directories without proper access permissions or authentication. A local attacker sharing the same system can connect to these endpoints to achieve arbitrary code execution or access sensitive workspace data with the permissions of the user running Nx.
Statement
This issue affects the Nx build tooling daemon and plugin-worker Unix sockets. In Red Hat products where Nx appears in source manifests (including Grafana, Ansible Automation Platform UI components, and related offerings), Nx is used only as a build-time or development dependency and is not present or executed in the shipped product. Customers running the delivered packages or images are not exposed to this vulnerability. The services-management-platform javascript-clients component already includes a fixed Nx version.
Mitigation
Red Hat is not aware of any mitigation or workaround that addresses this vulnerability at this time. Customers are advised to apply the relevant security update once 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.
CVSS v3 Score Breakdown

Vector
Red Hat: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Red Hat CVSS v3 Score Explanation
AV:L - local access to shared host/build server required. AC:L - no special conditions once another local account exists and Nx daemon/plugin-worker sockets are present. PR:L - unprivileged local peer. UI:N - no interaction needed. S:U - impact confined to the account running Nx. C/I/A:H - PROCESS_IN_BACKGROUND allows arbitrary code execution as the Nx user.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Since the file is visible and the application which is using the temp file could be known, the attacker has gained information about what the user is doing at that time.
