Bumps [handlebars](https://github.com/wycats/handlebars.js) from 4.0.12 to 4.1.2. <details> <summary>Changelog</summary> *Sourced from [handlebars's changelog](https://github.com/wycats/handlebars.js/blob/master/release-notes.md).* > ## v4.1.2 - April 13th, 2019 > Chore/Test: > - [#1515](https://github-redirect.dependabot.com/wycats/handlebars.js/pull/1515) - Port over linting and test for typings ([@&#8203;zimmi88](https://api.github.com/users/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](https://github-redirect.dependabot.com/wycats/handlebars.js/issues/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). > > [Commits](https://github.com/wycats/handlebars.js/compare/v4.1.1...v4.1.2) > > ## v4.1.1 - March 16th, 2019 > Bugfixes: > - fix: add "runtime.d.ts" to allow "require('handlebars/runtime')" in TypeScript - 5cedd62 > > Refactorings: > - replace "async" with "neo-async" - 048f2ce > - use "substring"-function instead of "substr" - 445ae12 > > Compatibility notes: > - This is a bugfix release. There are no breaking change and no new features. > > > [Commits](https://github.com/wycats/handlebars.js/compare/v4.1.0...v4.1.1) > > ## v4.1.0 - February 7th, 2019 > New Features > > - import TypeScript typings - 27ac1ee > > Security fixes: > > - disallow access to the constructor in templates to prevent RCE - 42841c4, [#1495](https://github-redirect.dependabot.com/wycats/handlebars.js/issues/1495) > > Housekeeping > > - chore: fix components/handlebars package.json and auto-update on release - bacd473 > - chore: Use node 10 to build handlebars - 78dd89c > - chore/doc: Add more release docs - 6b87c21 > ></tr></table> ...
