I think the bug has been fixed with latest tomcat version 9.0.33.

The multi-part file upload functionality which was not working in version 9.0.31, has also been fixed with the upgrade. Also, I have tried checking if there are any vulnerability using owasp dependency checker and found that there are no vulnerabilities in this version.

Just upgrade your dependency with the below version:

<!-- https://mvnrepository.com/artifact/org.apache.tomcat.embed/tomcat-embed-core -->
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-core</artifactId>
    <version>9.0.33</version>
</dependency>
