Improper Input Validation

scratch-vm is a Virtual Machine for Scratch 3.0

Affected versions of this package are vulnerable to Improper Input Validation. When loading an SB3, it is determined whether a block is part of an extension by inspecting its "extended" opcode (for example, pen_clear requires the pen extension). The extension ID is not sanitised, and some characters may cause potential problems.

How to fix Improper Input Validation?

Upgrade scratch-vm to version 0.2.0-prerelease.20200714185213 or higher.
