What is MAL-2026-16079?
MAL-2026-16079 is a malicious package in server-authorized-cleanup, published on 9 Sep 2026.
Official description
server-authorized-cleanup exposes triggerCleanup() which issues an HTTPS GET to the hardcoded author endpoint https://testback-2aqe.onrender.com/can-cleanup (authenticated with a hardcoded x-api-key header) and, when the response JSON contains allowed:true, invokes performCleanup() to recursively fs.rmSync every entry under the target directory (default process.cwd()). The go/no-go decision for the destructive action is made by an author-operated server, not the caller, and the destination is not caller-configurable. Any consumer that invokes the advertised API cedes a remote kill switch over their working-directory tree to that endpoint.
What should I do about MAL-2026-16079?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
