[Security] Bump xmlhttprequest-ssl from 1.5.5 to 1.6.3

[dependabot-preview]

Bumps xmlhttprequest-ssl from 1.5.5 to 1.6.3. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Improper Certificate Validation in xmlhttprequest-ssl The xmlhttprequest-ssl package before 1.6.1 for Node.js disables SSL certificate validation by default, because rejectUnauthorized (when the property exists but is undefined) is considered to be false within the https.request function of Node.js. In other words, no certificate is ever rejected.

Affected versions: < 1.6.1

Sourced from The GitHub Security Advisory Database.

Arbitrary Code Injection This affects the package xmlhttprequest before 1.7.0; all versions of package xmlhttprequest-ssl. Provided requests are sent synchronously (async=False on xhr.open), malicious user input flowing into xhr.send could result in arbitrary code being injected and run.

Affected versions: < 1.6.2
