Vulnerabilities that will be fixed

By pinning:

Severity	Issue	Upgrade	Breaking Change	Exploit Maturity
	Regular Expression Denial of Service (ReDoS) SNYK-PYTHON-BLEACH-561754	bleach: 3.1.0 -> 3.1.4	No	Proof of Concept

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.
