They excpect fame and may make things look worse than they are
No, they aren't. The website doesn't list an author, so fame is out of the question, and they say exactly how severe the bug is rated ("Rated 9.2 Critical (CVSS 4.0) by GitHub, High by Node.js.") right at the top.
How, exactly, are they making "things look worse than they are"? By.... showing what the issue is?
