[dependabot-preview]

Bumps handlebars from 4.7.6 to 4.7.7. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Remote code execution in handlebars when compiling templates The package handlebars before 4.7.7 are vulnerable to Remote Code Execution (RCE) when selecting certain compiling options to compile templates coming from an untrusted source.

Affected versions: < 4.7.7

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.

Quantification details

Label      : No Changes

Change counts above are quantified counts, based on the PullRequestQuantifier customizations.

Why proper sizing of changes matters

Optimal pull request sizes drive a better predictable PR flow as they strike a
balance between between PR complexity and PR review overhead. PRs within the
optimal size (typical small, or medium sized PRs) mean:

• Fast and predictable releases to production:
  • Optimal size changes are more likely to be reviewed faster with fewer
    iterations.
  • Similarity in low PR complexity drives similar review times.
• Review quality is likely higher as complexity is lower:
  • Bugs are more likely to be detected.
  • Code inconsistencies are more likely to be detetcted.
• Knowledge sharing is improved within the participants:
  • Small portions can be assimilated better.
• Better engineering practices are exercised:
  • Solving big problems by dividing them in well contained, smaller problems.
  • Exercising separation of concerns within the code changes.

What can I do to optimize my changes

• Use the PullRequestQuantifier to quantify your PR accurately
  • Create a context profile for your repo using the context generator
  • Exclude files that are not necessary to be reviewed or do not increase the review complexity. Example: Autogenerated code, docs, project IDE setting files, binaries, etc. Check out the Excluded section from your prquantifier.yaml context profile.
  • Understand your typical change complexity, drive towards the desired complexity by adjusting the label mapping in your prquantifier.yaml context profile.
  • Only use the labels that matter to you, see context specification to customize your prquantifier.yaml context profile.
• Change your engineering behaviors
  • For PRs that fall outside of the desired spectrum, review the details and check if:
    • Your PR could be split in smaller, self-contained PRs instead
    • Your PR only solves one particular issue. (For example, don't refactor and code new features in the same PR).

How to interpret the change counts in git diff output

• One line was added: +1 -0
• One line was deleted: +0 -1
• One line was modified: +1 -1 (git diff doesn't know about modified, it will
  interpret that line like one addition plus one deletion)
• Change percentiles: Change characteristics (addition, deletion, modification)
  of this PR in relation to all other PRs within the repository.
