What is MAL-2026-4685?
MAL-2026-4685 is a malicious package in tempo-components, published on 25 May 2026.
Official description
The package contains a file (poc.js) that imports os, https, fs, and child_process; collects host identifiers including os.hostname(), os.platform(), and the output of
whoami; and POSTs the data via https.request to an external endpoint. This is a classic system-reconnaissance and exfiltration shape with no benign interpretation for a package distributed under a 'components' name. Installing or loading this code on a build or developer machine causes host metadata and identity information to be transmitted off-host.What should I do about MAL-2026-4685?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
