Flaw, bug, and security vulnerability are intermixed in the article. This is a mature field. The word choice should be consistent, and it stinks of poor quality when someone chooses to treat them as if they are technically interchangeable problems.

I don't think so. A security vulnerability is a kind of bug, and a bug is a kind of flaw. Once you've introduced a problem using the most specific terminology, it's OK to refer to it using less specific terminology. It can help you avoid sounding repetitive.

(This reminds me of one of my kids at a very young age. If you said "I like your trousers", she'd reply "they're not trousers, they're jeans". But, of course, jeans are a kind of trousers, and it isn't mandatory to be as specific as possible at all times).

Software bug is just one area in the venn diagram of security vulnerability. Include areas outside of this such as insecure default settings, misconfigurations, major design weaknesses, hardware exploitations, etc. and you see my point.
