Security patches for Hybris versions higher than 5.3?

All information that I have found regarding security patches leads me to this website: https://wiki.hybris.com/display/downloads/Security+Patch+Downloads

In this website only appear patches until Hybris 5.3. Do not exists security patches for later versions?

I know that there are many patches for Hybris versions higher than 5.3 in their respective pages, but I'm looking specifically for security Patches. Are security issues now included in normal patches?

For example, looking at this website: https://wiki.hybris.com/display/downloads/Archived+5.7.0+Release

Since I can't find any specific security patch for Hybris 5.7. Should I be concern for Hybris security if I have Hybris version 5.7.0.1?

Thanks, Rafael
