Your audit is flawed. It is not enough to only check for version numbers. Package maintainers of large distributions backport all security fixes to the versions that are actively maintained.
You can see the fixes that have been applied in the changelog of the package. As long you install security updates you will also receive security fixes, even when the original software has them fixed in a newer version.
Currently the latest version of the Ubuntu 22.04 Apache package is 2.4.52-1ubuntu4.7. Since you are already on that version, all known security issues are fixed. The most relevant version number in here is the last part, ubuntu4.7.
If you want to know if a security issue exists, get the CVE number of the issue and check it agains the changelog. They are usually fixed and provided as an updated package very fast.
