Vulnerabilities that will be fixed

By pinning:

Severity	Priority Score (*)	Issue	Upgrade	Breaking Change	Exploit Maturity
	479/1000 Why? Has a fix available, CVSS 5.3	Regular Expression Denial of Service (ReDoS) SNYK-PYTHON-URLLIB3-1533435	urllib3: 1.25.11 -> 1.26.5	No	No Known Exploit

(*) 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 affected dependencies could be upgraded.
