DescriptionCVE.org

npm cli Incorrect Permission Assignment Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of npm cli. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

The specific flaw exists within the handling of modules. The application loads modules from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of a target user. Was ZDI-CAN-25430.

Executive ViewAI

Why It Matters

A local privilege escalation vulnerability in npm cli (CVE-2026-0775) could allow attackers with local system access to gain elevated privileges. This poses a direct risk to development teams and CI/CD pipelines, potentially compromising build integrity and enabling lateral movement within the organization.

Business Impact: High
Compensating Controls

Restrict npm cli execution to specific trusted user accounts; disable auto-update and global installation features; implement file permission monitoring on npm directories (/usr/local/lib/node_modules and ~/.npm); enforce sudo restrictions for npm operations; isolate development environments with network segmentation; conduct monthly privilege access reviews for development staff; monitor system logs for privilege escalation attempts.

Attack Technique

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
