A program running in Wine has all the power of the user it runs as. If
you run it as you, it can do anything you can.

Wine slightly sandboxes Windows applications, but it *does not*
promise security - because it can't promise security. A "Windows"
binary running under Wine can still execute an INT 0x80 to run a Linux
system call, and break out of .wine and do anything on the system that
the user it's running as can do.

c.f. ZeroWine, a system for testing viruses and malware (known
malicious software) in Wine - it runs Wine in Debian in QEMU,
completely isolated from the host system, to avoid it doing anything
horrible.
