GHSA-2HPJ-G53M-9GJ6
Vulnerability from github – Published: 2019-02-18 23:58 – Updated: 2023-09-08 20:52Affected 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:
1. Install the package using npm's --ignore-scripts flag.
2. Navigate to the package directory, and open default-config.json in a text editor
3. Change the download URLs in the compiler_url and library_url to https equivalents
4. run npm i in the package directory.
