Package	Affected versions	Patched versions
closure-util openlayers	`≤ 1.26.0`	No fix yet
closure-util npm	`≤ 2.0.0-beta.1`	No fix yet

Description

Affected versions of closure-util insecurely download an executable over an unencrypted HTTP connection.

In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running closure-util.

Recommendation

To mitigate this issue:

Install the package using npm's --ignore-scripts flag.
Navigate to the package directory, and open default-config.json in a text editor
Change the download URLs in the compiler_url and library_url to https equivalents
run npm i in the package directory.

NVD description

closure-utils is Utilities for Closure Library based projects. closure-utils downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.
