PgBouncer missing authorization check in KILL_CLIENT admin command
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
PgBouncer before 1.25.2 did not perform an appropriate authorization check for the KILL_CLIENT admin command. All users with access to the administration console (which itself requires authorization) could run this command. It would have been correct to allow only users listed in the admin_users parameter.
