Sourced from handlebars's changelog.

v4.1.2 - April 13th, 2019

Chore/Test:

• #1515 - Port over linting and test for typings (@​zimmi88)
• chore: add missing typescript dependency, add package-lock.json - 594f1e3
• test: remove safari from saucelabs - 871accc

Bugfixes:

• fix: prevent RCE through the "lookup"-helper - cd38583

Compatibility notes:

Access to the constructor of a class thought {{lookup obj "constructor" }} is now prohibited. This closes
a leak that only half closed in versions 4.0.13 and 4.1.0, but it is a slight incompatibility.

This kind of access is not the intended use of Handlebars and leads to the vulnerability described
in #1495. We will not increase the major version, because such use is not intended or documented,
and because of the potential impact of the issue (we fear that most people won't use a new major version
and the issue may not be resolved on many systems).
