What is MAL-2026-15511?

MAL-2026-15511 is a malicious package in intuit-authz, published on 28 Aug 2026.

Official description

package.json at line 11 declares a self-named dependency intuit-authz whose source is the bare HTTPS URL https://repo.securityctrl.com/intuit-authz instead of a semver range resolved through the npm registry. On npm install, npm fetches whatever bytes that URL currently serves and installs them, running any lifecycle scripts contained in the fetched tarball. The reference is unpinned, has no integrity hash, and points at a host unrelated to Intuit's published domains, so the operator of repo.securityctrl.com controls code executed on every installer's machine. The self-named key (intuit-authz declaring intuit-authz as a dependency) combined with a version number (55.0.0) implausibly high for a package under this name matches the dependency-confusion shape targeting an internal Intuit authorization package.

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-2026-15511?

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