BREAKING CHANGES:

• access to prototype properties is forbidden completely by default,
  specific properties or methods can be allowed via runtime-options.
  See #​1633 for details.
  If you are using Handlebars as documented, you should not be accessing prototype
  properties from your template anyway, so the changes should not be a problem
  for you. Only the use of undocumented features can break your build.

  That is why we only bump the minor version despite mentioning breaking changes.

Commits

v4.5.3

Compare Source

Bugfixes:

• fix: add "no-prototype-builtins" eslint-rule and fix all occurences - f7f05d7
• fix: add more properties required to be enumerable - 1988878

Chores / Build:

• fix: use !== 0 instead of != 0 - c02b05f
• add chai and dirty-chai and sinon, for cleaner test-assertions and spies,
  deprecate old assertion-methods - 93e284e, 886ba86, 0817dad, 93516a0

Security:

• The properties __proto__, __defineGetter__, __defineSetter__ and __lookupGetter__
  have been added to the list of "properties that must be enumerable".
  If a property by that name is found and not enumerable on its parent,
  it will silently evaluate to undefined. This is done in both the compiled template and the "lookup"-helper.
  This will prevent new Remote-Code-Execution exploits that have been
  published recently.

Compatibility notes:

• Due to the security-fixes. The semantics of the templates using
  __proto__, __defineGetter__, __defineSetter__ and __lookupGetter__ in the respect that those expression now return
  undefined rather than their actual value from the proto.
• The semantics have not changed in cases where the properties are enumerable, as in:

{
  __proto__: 'some string';
}

• The change may be breaking in that respect, but we still only
  increase the patch-version, because the incompatible use-cases
  are not intended, undocumented and far less important than fixing
  Remote-Code-Execution exploits on existing systems.

Commits

v4.3.0

Compare Source

Fixes:

• Security: Disallow calling "helperMissing" and "blockHelperMissing" directly - 2078c72
• Disallow calling "helperMissing" and "blockHelperMissing" directly - 2078c72

Features:

• Add new runtime option allowCallsToHelperMissing to allow calling blockHelperMissing and helperMissing.

Breaking changes:

Compatibility notes:

• Compiler revision increased - 06b7224

  • This means that template compiled with versions prior to 4.3.0 will not work with runtimes >= 4.3.0
    The increase was done because the "helperMissing" and "blockHelperMissing" are now moved from the helpers
    to the internal "container.hooks" object, so old templates will not be able to call them anymore. We suggest
    that you always recompile your templates with the latest compiler in your build pipelines.

• Disallow calling "helperMissing" and "blockHelperMissing" directly - 2078c72

  • Calling "helperMissing" and "blockHelperMissing" directly from a template (like in {{blockHelperMissing}} was
    never intended and was part of the exploits that have been revealed early in 20https://github.com/handlebars-lang/handlebars.js/issues/1495s.js/issues/1495). It is also part of a new exploit that
    is not captured by the earlier fix. In order to harden Handlebars against such exploits, calling thos helpers
    is now not possible anymore. Overriding those helpers is still possible.
  • If you really need this behavior, you can set the runtime option allowCallsToHelperMissing to true and the
    calls will again be possible

Both bullet points imly that Handlebars is not 100% percent compatible to 4.2.0, despite the minor version bump.

We consider it more important to resolve a major security issue than to maintain 100% compatibility.

#​1540 - added browser to package.json, resolves #​1102 (@​ouijan)

Compatibility notes:

• We are not sure if imports via webpack are still working, which is why this release is a pre-release

Compatibility notes:

Commits

v4.1.0

Compare Source

New Features

• import TypeScript typings - 27ac1ee

Security fixes:

• disallow access to the constructor in templates to prevent RCE - 42841c4, #​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

Compatibility notes:

Access to class constructors (i.e. ({}).constructor) is now prohibited to prevent
Remote Code Execution. This means that following construct will no work anymore:

class SomeClass {
}

SomeClass.staticProperty = 'static'

var template = Handlebars.compile('{{constructor.staticProperty}}');
document.getElementById('output').innerHTML = template(new SomeClass());
// expected: 'static', but now this is empty.

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).
