Background

@cecm-web-sdk/core is an npm package written in JavaScript. The supplied advisory identifies it as containing malicious code. The available information does not describe the package’s intended functionality or where it is used, so those details are not published.

Vulnerability Detail

The package contains embedded malicious code that may give an outside entity full control of a computer where it is installed or running. This can expose secrets and keys stored on that computer. Removing the package is necessary, but may not remove other malicious software introduced during installation. The advisory treats any computer with the package installed or running as fully compromised.

How To Fix

This package is malicious. Remove it and rotate any credentials it could have accessed.

npm uninstall @cecm-web-sdk/core

If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.

Workaround

Documented workaround: Remove @cecm-web-sdk/core and rotate all secrets and keys stored on the affected computer immediately, using a different computer. Because full control may have been given to an outside entity, removing the package does not guarantee that all resulting malicious software is removed.

Conclusion

No fixed version is published for @cecm-web-sdk/core. Remove the package, treat computers where it was installed or running as compromised, and rotate stored secrets and keys from a different computer. Removal alone may not eliminate malicious software introduced during installation. Vulert monitors the dependencies in package-lock.json and alerts when a new vulnerability affects them; check an application at https://vulert.com/scanner.
