GMS-2021-23: Improper Neutralization of Special Elements used in a Command ('Command Injection') in @floffah/build

May 28, 2021

Impact

If you are using the esbuild target or command you are at risk of code/option injection. Attackers can use the command line option to maliciously change your settings in order to damage your project.

Patches

The problem has been patched in v1.0.0 as it uses a proper method to pass configs to esbuild/estrella.

Workarounds

There is no work around. You should update asap.

Notes

This notice is mainly just to make sure people update to the latest version. This isn’t that bad, but should encourage you to update.
