Well, it's not April 1, so it's definitely true. And this vulnerability does exist. So everyone who has 7-zip older than ver 24.07 should update it. About WinRar - well yes, for me it was also the first archiver program, there were no alternatives in those days. (except WinZip)...But now you can't do without 7-zip, especially when it comes to the segment of games, all kinds of modpacks and modified games, where 7-zip has long become an unofficial “industry standard” and where old WinRar, often, just can't cope with unpacking such 7-zip archives.
