Definitely a Denial of Service issue here.

I feel like it could be all of the above, but that seems too broad. I need to think more about the specific vulnerabilities.

I'm leaning towards option B, access control, since it seems like a common vulnerability in similar examples we've studied.

I remember a practice question that mentioned denial of service attacks, but I can't recall if it applies here.

I think this code might be vulnerable to race conditions, but I'm not entirely sure how to identify them in this context.
