CVE-2026-0775: npm cli Incorrect Permission Assignment Local Privilege Escalation Vulnerability

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.

Security readout for executives and security teams

Plain-English summary

This is a local privilege escalation issue in npm CLI. A person who can already run low-privileged code on a machine may be able to make npm load code from an unsafe module location and run it as another target user. It matters most on shared developer systems, CI runners, and build servers.

Executive priority

Treat as high priority for shared development and build infrastructure because compromise can cross from low-privileged code to a target user. For isolated single-user systems, urgency is lower but inventory and vendor tracking are still needed.

Technical view

CVE-2026-0775 affects npm CLI 10.9.0 per the bundle. The flaw is incorrect permission assignment involving module handling: npm loads modules from an unsecured location, enabling local authenticated code execution in the target user's context. CVSS is 7.0 high with local attack vector, high complexity, low privileges, and high CIA impact.

Likely exposure

Exposure is most plausible where npm CLI 10.9.0 is installed on multi-user hosts, shared CI/build runners, or developer machines where low-privileged code can execute. The bundle does not establish broader version impact beyond 10.9.0, and default affected status is unknown.

Exploitation context

The sources describe a local attack requiring prior ability to run low-privileged code. There is no KEV listing in the bundle and no cited source here confirms active exploitation. The attack is high complexity but can result in arbitrary code execution as the target user.

Researcher notes

The bundle attributes the issue to unsecured module loading and CWE-732. Evidence is incomplete on fixed versions, exploit availability, and full affected-version range. Red Hat references and VEX data are listed, but this analysis should not assume remediation details absent from the provided sources.

Mitigation direction

  • Inventory hosts and build images for npm CLI 10.9.0.
  • Check npm, ZDI, and Red Hat guidance for fixed packages or vendor mitigations.
  • Avoid running npm as privileged users on shared systems.
  • Restrict untrusted local code execution on CI runners and developer hosts.
  • Prioritize rebuilds of base images once vendor-fixed npm packages are available.

Validation and detection

  • Confirm npm CLI versions on developer workstations, servers, and CI images.
  • Identify systems where low-privileged users or jobs can run local code.
  • Review build workflows that execute npm under privileged or shared target accounts.
  • Track ZDI, CVE, and Red Hat records for patch or impact updates.
  • Document whether each exposed environment is single-user, shared, or CI-controlled.
