Because WinRAR is popular and I have not seen it posted as much? My motive was to spread awareness, because of its sheer popularity. I see no harm in this.
This CVE being a month old does not mean its an outdated thing, because the potential of users getting affected is massive. Too many RAR 3.x and older packaged archives circulate around the world, and WinRAR does not automatically update for people, unless you are a techie that uses winget or choco.
I remain on top of such news usually, and if I missed it, there is a very good chance many have. Yes, I see myself as a benchmark of sorts, considering how seriously I treat and advocate privacy and security. If you want to just look good for calling me as a mod out, it is very unnecessary, unless there is some malicious intent or a low effort post being made.
Edit: you say it was posted “a lot” on Lemmy. But I only see one post each on Beehaw and Lemmy.world, which, for a CVE of this potential is… very bad? This news should have been plastered all over in relevant tech subs for maximum awareness.
