What is MAL-2026-15523?

MAL-2026-15523 is a malicious package in sycm-vendors, published on 28 Aug 2026.

Official description

package.json declares a self-named dependency 'sycm-vendors' whose source is the bare URL https://repo.securityctrl.com/sycm-vendors rather than a registry version range, with no version pin and no integrity hash. On npm install, npm resolves this URL and installs whatever tarball the host returns, executing any lifecycle scripts contained in that tarball. The dependency key equals the package's own name (dependency-confusion shape), and the shipped index.js is an inert stub, so the manifest is the entire payload-delivery mechanism — control of repo.securityctrl.com equates to arbitrary code execution on any installer.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

What should I do about MAL-2026-15523?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
