Vinegar is greatly diluted acetic acid. Something around 5% acidity. Acetic acid
can also be 20%, 50%,100%, or anything in between, all which might surprise you
with their effects on metals including stainless.

Where does one buy the higher concentrations? I'm looking for something to
apply to the aluminum stanchion bases in order to get loose the stainless
bolts securing the stanchions to the bases. Might the higher concentrations
of acetic be what I'm looking for?

I don't know. Have you tried PB Blaster, and a hammer driven impact
driver?

If you want to try a strong acid, use the stuff they sell for
dissolving barnacles. Just be very careful with it, and don't
accidentally inhale the fumes.

Hydrochloric, sold as muratic for cleaning mortar from bricks, and for
adjusting the acidity of swimming pools.
