[dependabot]

Bumps jszip from 2.6.1 to 3.7.0.

Changelog

Sourced from jszip's changelog.

v3.7.0 2021-07-23

• Fix: Use a null prototype object for this.files (see #766)
  • This change might break existing code if it uses prototype methods on the .files property of a zip object, for example zip.files.toString(). This approach is taken to prevent files in the zip overriding object methods that would exist on a normal object.

v3.6.0 2021-02-09

• Fix: redirect main to dist on browsers (see #742)
• Fix duplicate require DataLengthProbe, utils (see #734)
• Fix small error in read_zip.md (see #703)

v3.5.0 2020-05-31

• Fix 'End of data reached' error when file extra field is invalid (see #544).
• Typescript definitions: Add null to return types of functions that may return null (see #669).
• Typescript definitions: Correct nodeStream's type (see #682)
• Typescript definitions: Add string output type (see #666)

v3.4.0 2020-04-19

• Add Typescript type definitions (see #601).

v3.3.0 2020-04-1

• Change browser module resolution to support Angular packager (see #614).

v3.2.2 2019-07-04

• No public changes, but a number of testing dependencies have been updated.
• Tested browsers are now: Internet Explorer 11, Chrome (most recent) and Firefox (most recent). Other browsers (specifically Safari) are still supported however testing them on Saucelabs is broken and so they were removed from the test matrix.

• Corrected built dist files

v3.2.0 2019-02-21

• Update dependencies to reduce bundle size (see #532).
• Fix deprecated Buffer constructor usage and add safeguards (see #506).

v3.1.5 2017-11-09

• Fix IE11 memory leak (see #429).
• Handle 2 nodejs deprecations (see #459).
• Improve the "unsupported format" error message (see #461).
• Improve webworker compatibility (see #468).
• Fix nodejs 0.10 compatibility (see #480).
• Improve the error without type in async() (see #481).

v3.1.4 2017-08-24

• consistently use our own utils object for inheritance (see #395).
• lower the memory consumption in generate* with a lot of files (see #449).

v3.1.3 2016-10-06

@optilude any chance of getting this merged in? There's a vulnerability in jszip@2.6.1 (https://nvd.nist.gov/vuln/detail/CVE-2021-23413).
If you need help getting this version tested etc please let us know we can raise an updated PR as required

[kant2002]

@jmac105 seems to be it's time to break backward compatibility. JSzip moves from sync implementation altogether, and I postpone update decision to update, hoping that one day I will come up with solution.

If you know specfic change which fix vulnerability, I prefer to temporary fork jszip, so existing user would not be affected by update

[kant2002]

If somebody know, is https://github.com/abbr/deasync would be a good choice as a stopgap solution to temporary provide sync interface?
Seems to be I found the fix is here Stuk/jszip#766

[kant2002]

I hope that Stuk/jszip#824 will fix the issue.
