Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
windows-build-tools is a module for installing C++ Build Tools for Windows using npm. windows-build-tools versions below 1.0.0 download 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 resources with an attacker controlled copy if the attacker is on the network or positioned in between the user and the remote server.
