--- Comment #2 from Jeremy Harris <jgh146exb@???> ---
Vulnerable since intro of the external authenticator in 4.93

One-liner fix. We're only expecting one supplied parameter, so nail the
param count to 1 before expanding server_param{2,3} and writing into those
arrays using that count value (bumped).
