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).
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
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.
