Composite door panel crack

[Wardyx]

Hi all.

I’m very new to this site and I was looking for some advice. My wife has noticed a crack or something within the border panel around the windows in our composite door. She is very worried that someone may be trying to break into the door via this way but I’m not sure, I’m looking for some advice whether this happens with these type of doors or could she be right?

This all is on the left side and the right side is fine?

If it is also something that does happen would some simple glue be a fix??

No its more likely and expansion/contraction crack, being black or just being dark means it absorbs a lot of heat, is it south facing or there abouts? If someone were trying to force that cassette off they'd be more damage to the area.
