I totally agree that appending in SoftMaker Office to the title does change the meaning dramatically. it narrows down the vulnerability to a specific product that uses the MSI installer but not the MSI as a technology.
I tried to submit a story with a lengthy title a couple of days ago and HN refused to accept it until I'd cut it down. So it's probably the submitter's doing.
Title taken from their page:
> Local Privilege Escalation via MSI installer in SoftMaker Office / FreeOffice
I despise click bait.
