CVE-2026-78204

5.4 · MEDIUM
Published Aug 24, 2026 CWE-862 EPSS 0.22% (13th pctl)

Overview

CVE-2026-78204 is a medium-severity vulnerability. It was published on August 24, 2026 and has a CVSS 3.1 base score of 5.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.4, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical Description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
