For your information, there is a vulnerability that could allow the sent file to be automatically executed when the user opens it.

It is also described as a “ spoofing ” issue, where files appear to be safe but are actually executable programs.
This issue affects WhatsApp version 2.2450.6 and below. Meta (the parent company of WhatsApp) received information about this bug through its bug bounty program from a security researcher.
