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 2019
(see wycats/handlebars.js#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.
