FKIE_CVE-2026-78204

Vulnerability from fkie_nvd - Published: 2026-08-24 01:16 - Updated: 2026-10-12 16:10
Severity
5.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
Summary
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.

RoleBasedAccessControlMixin.test_func devuelve solo request.user.is_active a menos que una vista lo anule, y ni el punto final que aplica lint a una plantilla de informe ni el punto final que devuelve los resultados de lint almacenados proporcionan una anulaci\u00f3n, por lo que cada uno resuelve un ReportTemplate a partir de una clave primaria proporcionada por el llamador sin verificaci\u00f3n de propiedad o de alcance del cliente. Cualquier cuenta autenticada puede, por lo tanto, aplicar lint a una plantilla arbitraria, lo que sobrescribe el resultado de lint almacenado de esa plantilla, y puede leer los hallazgos devueltos, que enumeran los nombres de las variables de la plantilla y los errores del motor de plantillas y as\u00ed revelan su estructura. Esto es distinto de la ruta de intercambio de plantillas: ese punto final autoriza el informe pero omite la verificaci\u00f3n por plantilla, mientras que estos puntos finales omiten la autorizaci\u00f3n por completo y permanecen sin corregir."
