The spring-boot-starter-parent at the top of your pom file manages the spring framework version. Change the version from 2.3.2.RELEASE to 2.3.12.RELEASE and the spring framework version will change to 5.2.15. You can use maven tools, including the dependency hierarchy in eclipse, to see how that works.

In your properties section, add this temporarily:

<spring-framework.version>5.2.20.RELEASE</spring-framework.version>

Check the spring boot wiki for the release notes for upgrading versions. When you are on a supported version then remove the spring-framework.version property.
