Executive Summary

CVE-2026-0775 is a local privilege escalation vulnerability in the npm CLI caused by incorrect permission assignment during module handling. The npm CLI loads modules from an unsecured location, which allows an attacker who already has the ability to execute low-privileged code on the system to escalate their privileges and execute arbitrary code with the privileges of the targeted user. [1]

Impact Analysis

This vulnerability can allow an attacker who has limited access to your system to escalate their privileges, potentially gaining higher-level access and executing arbitrary code with the privileges of the targeted user. This could lead to unauthorized actions, data compromise, or further system exploitation. [1]

Mitigation Strategies

To mitigate this vulnerability, ensure that you restrict the ability to execute low-privileged code on your system, as exploitation requires such access. Additionally, update the npm CLI to the latest version where this vulnerability is fixed or apply any vendor-provided patches. Review and correct permission assignments related to module handling to prevent loading modules from unsecured locations. [1]
