Although NotificationTemplate.notification_\n                  configuration is protected from API filtering, its recipient\n                  value is copied in clear text into the unprotected\n                  Notification.recipients field on every send. Because the\n                  credential-types endpoint is listable by any authenticated\n                  user and the API filter backend traverses object relations\n                  without per-hop authorization, a user with no privileges can\n                  use a relational filter as a boolean count-oracle to recover,\n                  character by character and across organizations, the secret\n                  recipient values of other tenants' notifications — including\n                  PagerDuty service keys and Slack/Mattermost/RocketChat/Webhook\n                  bearer-token URLs.
