No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Ghostwriter through 7.2.6 does not apply per-object authorization on its report template lint endpoints. RoleBasedAccessControlMixin.test_func returns only request.user.is_active unless a view overrides it, and neither the endpoint that lints a report template nor the endpoint that returns stored lint results provides an override, so each resolves a ReportTemplate from a caller-supplied primary key with no ownership or client-scope check. Any authenticated account can therefore lint an arbitrary template, which overwrites that template's stored lint result, and can read the returned findings, which enumerate the template's variable names and template-engine errors and so disclose its structure. This is distinct from the template swap path: that endpoint authorizes the report but omits the per-template check, whereas these endpoints omit authorization entirely and remain unfixed.
