Wikipedia:High-risk templates

Following the protection policy, page protection may be indefinitely applied to all templates, template redirects, and Lua modules that have been identified by the community as being of high risk to Wikipedia. If fully protected so that they can only be edited by administrators, or template-protected so that they can only be edited by administrators and template editors, these pages should be edited cautiously, and consensus should be established for any changes that might be controversial. If semi-protected or extended-confirmed protected, templates and modules may be edited by any established user, but users should ensure there is consensus for their edits and avoid edit wars.
