AI agents use unlink_asset_set_from_campaign to create or update resources in Google Ads — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Ads environment.
This operation modifies campaign configuration by removing an asset set link, which is a reversible change (the link can be re-established). It does not delete underlying data or execute arbitrary code, nor does it involve financial transactions. The moderate severity reflects that misconfiguration could disrupt ad delivery or campaign performance, but the change can be undone.
