And yes, people who get scared file reports asking us to fix it, oftentimes we can't (because it's not a real vuln), and 99% of the time they're not even remotely affected. The requests are generally not very nice, either.
Most of the time, the request to fix a CVE is the first we've ever heard of it being filed. "Security research agencies" oftentimes have their own databases, and rarely do these "researchers" follow any amount of responsible disclosure, let alone even telling us about their findings or that they've filed. Many of them don't even cite a reporter, email, or any such contact information.
Especially when the CVE is nonsense, improperly scored, etc. there is almost no way to get it taken down or to reduce its severity. Apparently in the eyes of these agencies the people writing the code cannot adequately gauge the severity of vulnerabilities. It's nearing levels of almost zero collaboration with maintainers before things are filed.
I can't remember the last time I even had the opportunity to release a proper fix before a CVE went out. I can count on one hand the number of times I was asked before a CVE was filed. I don't think a single CVE of any code I maintain has had a score that properly reflected the severity of the actual vulnerability (assuming there even was one).
Remember, most of us do this in free time, for free. So all of the extra bureaucracy and synthesized urgency can be extremely detrimental.
