Summary

Ghostwriter before 7.1.2 fails to validate template ownership in the report template swap endpoint, allowing attackers to attach client-scoped templates from other clients to their own reports. Attackers can exploit sequential template primary keys to enumerate and attach foreign templates, then generate reports to disclose template contents including letterhead, boilerplate, and methodology text.

Risk Assessment

The organization may be exposed to leakage of confidential information contained in other clients' report templates, potentially compromising data confidentiality or reputation.

Recommendation

It is recommended to update Ghostwriter to version 7.1.2 or later, which includes a fix for template ownership validation.

Other vulnerabilities in Ghostwriter

CVE-2026-78204Medium
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.
