Nx Nx Console

CVE-2026-48027 Added May 27, 2026 Remediation deadline has passed
TL;DR

Nx Nx Console is affected by a critical-severity vulnerability (CVE-2026-48027) that is confirmed to be actively exploited in the wild. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

What is this vulnerability?

Nx Console is the user interface for Nx & Lerna. On 19 May 2026, a malicious version of Nx Console, 18.95.0, was published at 12:30 PM UTC and removed soon after at 12:48 PM UTC, leaving it available for ~18 minutes in Visual Studio Marketplace. For OpenVSX, the problem was detected later, and the compromised version was available from 12:33 UTC to 13:09 UTC (~36 minutes). Version 18.100.0 of Nx Console is not compromised and users may remediate by upgrading to that version.

How it works

This is classified as CWE-506. In plain terms, an attacker could use this flaw in Nx Console to gain access, disrupt service, or steal data — the exact impact depends on how it’s deployed in your environment.

CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Required action

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Mitigations

  • Apply the vendor’s security patch or update as soon as it’s available and tested.
  • If no patch exists yet, apply the vendor’s temporary workaround.
  • Limit network exposure of the affected system until it’s patched.
  • Review logs for signs of prior exploitation, especially if it’s flagged for ransomware use.

Recommendations

  • Confirm whether Nx Nx Console is used anywhere in your environment.
  • Patch internet-facing systems first, then internal ones.
  • Set a reminder ahead of the remediation deadline so it doesn’t slip.
  • Subscribe to the vendor’s security advisories for earlier warning next time.
