Reading the blog post, it’s a lot more nuanced than that: someone reported a CVE, which was related to a possible int overflow in client code handling the timeout between requests. NVD chose to grade this as a 9.8/10 on their severity scale (for context, CVE-2014-0160, also known as Heartbleed, got a 7.5/10), which is ludicrous for a bug which could at most change the retry timeout of your request from your intended years to a few seconds. Daniel says that this is not a security vulnerability at all and has no business being listed on the CVE database, whereas NVD argues that it’s a bug, it’s been reported to them and because overflows are undefined behavior, anything can happen and so it’s a security vulnerability.

In the end, they agreed to at least adjust the severity down to a 3.3, but I can understand that Daniel is still somewhat miffed about it. Personally I also agree that it’s not really a security issue and that even a 3.3 is too high in terms of severity.
