Subject: [PATCH] chore(gui): upgrade jQuery to 3.7.1 to fix CVE-2020-11022,
 CVE-2020-11023, CVE-2015-9251 (#10673)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

- Replace vendored `jquery-2.2.2.js` with `jquery-3.7.1.js` in
`gui/default/vendor/jquery/`
- Update script reference in `gui/default/index.html` to point to the
new file
- Update CDN reference in `cmd/infra/strelaypoolsrv/gui/index.html` from
`jquery-2.1.4.min.js` to `jquery-3.7.1.min.js`

## Why

The previously used jQuery versions (2.2.2 and 2.1.4) are vulnerable to
three known CVEs:

| CVE | Description | Fixed in |
|-----|-------------|----------|
| CVE-2015-9251 | XSS via cross-domain Ajax requests with non-text
content types | jQuery 3.0.0 |
| CVE-2020-11022 | XSS when passing HTML containing `<option>` elements
to manipulation methods | jQuery 3.5.0 |
| CVE-2020-11023 | XSS via passing HTML from untrusted sources to
manipulation methods | jQuery 3.5.0 |

jQuery 3.7.1 is the latest stable release and resolves all three.

## Compatibility notes

The GUI code was audited for jQuery 2→3 breaking changes. No removed
APIs are used:
- `.success()` / `.error()` calls throughout the codebase are
**AngularJS `$http`** promise methods, not jQuery — unaffected
- `.bind('beforeunload', ...)` is deprecated in jQuery 3 but not removed
— still works
- No usage of `.size()`, `.load()` event shorthand, `jQuery.isFunction`,
or `$.type()`
