      "value": "OpenProject is open-source, web-based project management software. Prior to 17.6.0, GET /api/v3/custom_options/:id resolved CustomOption records by global numeric id and allowed UserCustomField and GroupCustomField options without checking visible(current_user), so authenticated non-admin users could enumerate sequential custom option ids and read labels belonging to admin_only user or group custom fields. This issue is fixed in 17.6.0."

Antes de la versión 17.6.0, GET /API/v3/custom_options/:id resolvía registros de CustomOption por ID numérico global y permitía opciones de UserCustomField y GroupCustomField sin verificar visible(current_user), por lo que los usuarios autenticados no administradores podían enumerar IDs de opciones personalizadas secuenciales y leer etiquetas pertenecientes a campos personalizados de usuario o grupo admin_only. Este problema está solucionado en la versión 17.6.0."
