What is MAL-2026-15519?
MAL-2026-15519 is a malicious package in qbo-ui-services, published on 28 Aug 2026.
Official description
package.json line 11 declares a self-referential dependency whose source is a bare HTTP URL rather than a registry version range: "qbo-ui-services": "https://repo.securityctrl.com/qbo-ui-services". On npm install, npm fetches whatever tarball that URL returns and installs it, executing any lifecycle scripts contained inside, with no version pin and no integrity hash. The shipped index.js is an inert stub, so the manifest line is the entire published payload. The dependency key equals this package's own name and the version marker (45.0.0) is implausibly high, matching a dependency-confusion shape intended to win resolution against an internal package. The host repo.securityctrl.com is not a known npm registry and is unrelated to any declared repository or homepage.
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-2026-15519?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
