#### Vulnerabilities that will be fixed
##### By pinning:
Severity | Priority Score (*) | Issue | Upgrade | Breaking Change | Exploit Maturity

 | **611/1000** **Why?** Recently disclosed, Has a fix available, CVSS 6.5 | Denial of Service (DoS) [SNYK-PYTHON-CRYPTOGRAPHY-5914629](https://snyk.io/vuln/SNYK-PYTHON-CRYPTOGRAPHY-5914629) | `cryptography:` `37.0.4 -> 41.0.4` | 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.
Check the changes in this PR to ensure they won't cause issues with your project.
