How to fix?

Upgrade nuclide to version 0.290.0 or higher.

Overview

nuclide is a collection of features for Atom to provide IDE-like functionality for a variety of programming languages and technologies.

Affected versions of this package are vulnerable to Arbitrary Code Execution. The hhvm-attach deep link handler in Nuclide did not properly sanitize the provided hostname parameter when rendering. As a result, a malicious URL could be used to render HTML and other content inside of the editor's context, which could potentially be chained to lead to code execution.
