What is MAL-2026-10530?
MAL-2026-10530 is a malicious package in cbr-internal-utils, published on 14 Jul 2026.
Official description
On module load, the package's main entrypoint shells out via child_process.exec to run
cat /etc/passwd and prints the contents to stdout. This fires unconditionally when any consumer require()s the package — no user action or configuration is needed. The package has an internal-sounding name and empty author/description metadata, consistent with a dependency-confusion probe or reconnaissance payload rather than a legitimate library. Reading /etc/passwd serves no library purpose and enumerates local user accounts on the installer's host.What should I do about MAL-2026-10530?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
