Nx Console Embedded Malicious Code Vulnerability
CVE-2026-48027 tracks a software supply-chain compromise of Nx Console, the user interface extension for Nx and Lerna. A malicious build, Nx Console version 18.95.0, was briefly published to the Visual Studio Marketplace on 2026-05-19 from 12:30 UTC to 12:48 UTC and to OpenVSX from 12:33 UTC to 13:09 UTC. The compromised extension was also reported as being distributable through VS Code’s automatic update mechanism to systems that already had Nx Console installed. According to the provided content, the malicious extension contained embedded malicious code and fetched an obfuscated secondary payload. That payload was capable of harvesting credentials from multiple sources on disk and in memory, including developer and cloud-related secrets. Additional reporting in the provided context states that when a developer opened a workspace with the compromised extension installed, the extension silently retrieved and executed the hidden payload, which targeted items such as GitHub tokens, AWS credentials, Kubernetes configuration, npm tokens, Vault secrets, and 1Password data. The issue is therefore not a conventional memory-corruption flaw in a legitimate code path, but a maliciously published trojanized extension release under a trusted distribution channel.
