Vulnerabilities that will be fixed

By pinning:

Severity	Priority Score (*)	Issue	Upgrade	Breaking Change	Exploit Maturity
	704/1000 Why? Has a fix available, CVSS 9.8	Arbitrary Code Execution SNYK-PYTHON-PYYAML-559098	pyyaml: 5.2 -> 5.3.1	No	No Known Exploit
	876/1000 Why? Mature exploit, Has a fix available, CVSS 9.8	Arbitrary Code Execution SNYK-PYTHON-PYYAML-590151	pyyaml: 5.2 -> 5.3.1	No	Mature

(*) Note that the real score may have changed since the PR was raised.

Some vulnerabilities couldn't be fully fixed and so Snyk will still find them when the project is tested again. This may be because the vulnerability existed within more than one direct dependency, but not all of the effected dependencies could be upgraded.
