When Voyager was out of contact and it was in the press, I was curious if
any of the Voyager computer details were public. I have not found much
detailed information online.
I don't think it is a security concern, who has a big enough antenna.

Sorry, I guess this should dead end, it is too

still post this since I was among those misled into thinking it had an 1802
microprocessor. The galileo had an 1802, but it suicided.
from Wikipedia:
It has been erroneously reported[41] on the Internet that the Voyager
space probes were controlled by a version of the RCA 1802 (RCA
CDP1802 "COSMAC" microprocessor), but such claims are not supported
by the primary design documents. The CDP1802 microprocessor was used
later in the Galileo space probe, which was designed and built years
later. The digital control electronics of the Voyagers were not based
on a microprocessor integrated-circuit chip.

NASA has an article about the Voyager computers (two each of three
different kinds) at
https://voyager.jpl.nasa.gov/frequently-asked-questions/
Look for the pop-open "What kind of computers are used on the Voyager
spacecraft?"
The last paragraph is "Voyager was built in-house at JPL; the computers
were manufactured by General Electric to JPL specifications."
