Technical Description
/misc/workspace/adhoc_connect_server, part of the Workspaces feature introduced in pgAdmin 4 9.0, when passed the id of an existing server, clones that server via Server.clone(), which copies every column from the source row, including user_id, shared, shared_username, and the stored credential fields password, save_password, and tunnel_password. When a non-owner triggered an adhoc connect against another user's (in practice, typically an administrator's) shared server, the clone inherited that user's ownership, shared flag, and stored database credentials verbatim. pgAdmin persisted this cross-tenant, credential-bearing server row before the connection was even attempted, so it survived even when the connection subsequently failed. The non-owner could then open the newly-owned clone and pgAdmin would connect using the source user's stored database password on the non-owner's behalf, granting the non-owner use of database credentials -- and whatever database privileges they confer -- t
