      "value": "OpenProject is open-source, web-based project management software. Prior to 17.3.2 and 17.4.0, a Missing Authorization vulnerability exists in OpenProject's CostReportsController. The rename and update actions allow any authenticated user to modify the name, filters, and grouping of any Public cost report in the system without verifying ownership or permission level. An attacker who discovers or guesses a public report's numeric ID can rename or overwrite its filter configuration without any warning to the report's owner. This vulnerability is fixed in 17.3.2 and 17.4.0."

Antes de las versiones 17.3.2 y 17.4.0, existe una vulnerabilidad de autorización faltante en el CostReportsController de OpenProject. Las acciones de renombrar y actualizar permiten a cualquier usuario autenticado modificar el nombre, los filtros y la agrupación de cualquier informe de costes público en el sistema sin verificar la propiedad o el nivel de permiso. Un atacante que descubre o adivina el ID numérico de un informe público puede renombrar o sobrescribir su configuración de filtro sin ninguna advertencia al propietario del informe. Esta vulnerabilidad está corregida en las versiones 17.3.2 y 17.4.0."
