The bootstrap command staged its script into C:\Windows\Temp and then ran it elevated. That directory grants Users create-file with CREATOR OWNER full control, so somebody without admin rights can pre-plant the exact path the elevated run is about to execute. It now stages under Program Files, creates the directory with an explicit DACL when it is missing, and refuses to run a staged file that is not owned by an admin principal. A failed hardening is loud rather than silent: the run stops instead of carrying on with a file it could not protect. The token moved out of the query string into a header. In a query string it lands verbatim in the reverse proxy and IIS logs, which is a credential written to a file nobody thinks of as a secret store. The query form is still accepted, because bays provisioned before this change are holding install commands that use it, and it logs that it was used - without logging the token - so a site can see who still needs a re-issued command before turning it off with plugin.endpoints.bootstrapquerytoken. Two smaller things this also closes: A request with no token at all answered 400 naming the header, which told an anonymous caller the state of that switch and contradicted the module's own promise that anything unusable answers 404. No token is now 404. The 400 is kept for a token genuinely presented in the query form while the query form is off, which is a caller who needs to know their command is stale. The rollout documentation was republishing the vulnerable one-liner verbatim, so a tech following the runbook reinstated exactly what this fixes. Both documents now carry the current command. Also corrects the operator-facing copy for the token, which named a query argument and a header that do not exist: it is ?t= and X-Endpoint-Bootstrap-Token, per bootstrap.py's own constants. Anybody following the old text got a 404 with no reason given. Both switches added in this range are now declared with the other plugin settings and reachable from their settings page. Read through Setting.get but never declared, they were rows that did not exist until someone wrote one by hand, which on an air-gapped box means the feature was unreachable.
