Whilst reading a paper I discovered another and I am now building upon the latter. Should I cite the former paper, since that's how I discovered the latter? Or does it suffice to cite only the latter?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Unless I misunderstand, the question comes down to "Publication A has cited Publication B, which is a primary source. Can I also cite Publication B, or would that be plagiarism?".
The answer is "Yes, it's fine for multiple people to cite the same primary source".
