Hi Peter,
do we talk about Article addon?
If yes, indeed text in "Read more" is short, if you would look into html code, you will see that there is
aria-label="Read more about: TITLE OF ARTILE" so for Accessibility purposes should be OK. In this case, aria-label adds context, because the text “Read more” alone is too general . At least WAVE tool say so.
If not, you can always disable "Read More", and keep only Title active link, this is also popular. I talk about current version, and without touching a php code.
Is there a way to solve this?
Yes, you have to override & customize Article addon code, edit site.php file.
