Yes, I would consider this bad design.
It may or may not be an actual problem depending on your application and on how much current is actually running through such spots (probably it's just a fraction of your board's total supply current).
But the voltage drop alone might be enough to disrupt the functionality of your board, e. g. offsetting the measurement of a sensitive ADC circuit. Or these spots might only heat up a little without destruction. But in your case this could reduce the life time of that capacitor. The most obvious problem are burning tracks, of course (probably not at 1.5 A).
I realize such spots can't be detected easily. The net list check of your CAD tool will have no reason to complain here, of course. You need heavy duty simulation tools to automatically detect such spots and predict how problematic they actually are.
But the minimum I would do is adding an item to your layout review checklist to increase the probability of finding such spots. Notice how there is also a bad spot next to the round trough hole pad, for example.
Also keep in mind that not only power but also signals need a return path. A messed up return path for signals could cause signal integrity and/or EMI issues.
