[Security] Bump handlebars from 4.0.11 to 4.7.7

Bumps handlebars from 4.0.11 to 4.7.7. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Prototype Pollution in handlebars Versions of handlebars prior to 3.0.8 or 4.5.3 are vulnerable to prototype pollution. It is possible to add or modify properties to the Object prototype through a malicious template. This may allow attackers to crash the application or execute Arbitrary Code in specific conditions.

Recommendation

Upgrade to version 3.0.8, 4.5.3 or later.

Affected versions: >= 4.0.0 < 4.5.3

Sourced from The GitHub Security Advisory Database.

Arbitrary Code Execution in handlebars Versions of handlebars prior to 3.0.8 or 4.5.2 are vulnerable to Arbitrary Code Execution. The package's lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript in the system. It can be used to run arbitrary code in a server processing Handlebars templates or on a victim's browser (effectively serving as Cross-Site Scripting).

The following template can be used to demonstrate the vulnerability:
    {{#with split as |a|}}
        {{pop (push "alert('Vulnerable Handlebars JS');")}}
        {{#with (concat (lookup join (slice 0 1)))}}
            {{#each (slice 2 3)}}
                {{#with (apply 0 a)}}
                    {{.}}
                {{/with}}
            {{/each}}
        {{/with}}
    {{/with}}
{{/with}}```
Recommendation
Upgrade to version 3.0.8, 4.5.2 or later.
Affected versions: >= 4.0.0 < 4.5.2

Sourced from The GitHub Security Advisory Database.

Denial of Service in handlebars Affected versions of handlebars are vulnerable to Denial of Service. The package's parser may be forced into an endless loop while processing specially-crafted templates. This may allow attackers to exhaust system resources leading to Denial of Service.

Recommendation

Upgrade to version 4.4.5 or later.

Affected versions: >= 4.0.0 < 4.4.5

Sourced from The GitHub Security Advisory Database.

Prototype Pollution in handlebars Versions of handlebars prior to 4.0.14 are vulnerable to Prototype Pollution. Templates may alter an Objects' prototype, thus allowing an attacker to execute arbitrary code on the server.

Recommendation

For handlebars 4.1.x upgrade to 4.1.2 or later. For handlebars 4.0.x upgrade to 4.0.14 or later.

Affected versions: >= 4.0.0 < 4.0.14

Sourced from The Node Security Working Group.

Denial of Service Crash Node.js process from handlebars using a small and simple source

Affected versions: <4.6.0

Sourced from The GitHub Security Advisory Database.

High severity vulnerability that affects handlebars Versions of handlebars prior to 4.3.0 are vulnerable to Prototype Pollution leading to Remote Code Execution. Templates may alter an Object's proto and defineGetter properties, which may allow an attacker to execute arbitrary code through crafted payloads.

Affected versions: < 4.3.0

Changelog

Sourced from handlebars's changelog.

v4.7.7 - February 15th, 2021

fix weird error in integration tests - eb860c0

fix: check prototype property access in strict-mode (#1736) - b6d3de7

fix: escape property names in compat mode (#1736) - f058970

refactor: In spec tests, use expectTemplate over equals and shouldThrow (#1683) - 77825f8

chore: start testing on Node.js 12 and 13 - 3789a30

(POSSIBLY) BREAKING CHANGES:

the changes from version 4.6.0 now also apply in when using the compile-option "strict: true". 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 patch version despite mentioning breaking changes.
