Reconmap 的 API 在 中应用了一种回退授权策略，该策略要求用户必须经过身份验证并拥有管理员角色，因此那些未定义自身授权属性的控制器会拒绝匿名访问。然而， 中的报告预览操作标记了 （允许匿名访问），从而绕过了上述回退授权策略。 函数通过 URL 路径段中的 参数加载对应名称的 Project（项目）记录，再通过项目的 加载关联的 Organisation（组织），然后将这两者渲染到 模板中。该模板会输出项目名称和描述，以及客户端组织的名称、地址和 URL。整个过程中未执行任何身份验证、项目成员资格检查或角

Vulnerability Title
Reconmap Report Preview Endpoint Is Marked AllowAnonymous, Exposing Every Project and Client Organisation Without Authentication
Source: CVE Program / CVE List V5
Vulnerability Description
Reconmap's API applies a fallback authorization policy in apps/api/app/Program.cs that requires an authenticated user holding the administrator role, so controllers without their own attribute reject anonymous callers. The report preview action in apps/api/app/Controllers/ReportsController.cs carries [AllowAnonymous] and therefore opts out of that policy. PreviewReport loads the Project row named by the id path segment, loads the linked Organisation through the project's ClientId, and renders both into default-report-template.html, which prints the project name and description together with the client organisation's name, address and URL. No authentication, project membership or role check is performed. Because the id is the auto-increment primary key of the project table, an unauthenticated remote caller can walk sequential ids to retrieve the engagement details and client organisation of every project on the instance, and the 404 returned for a missing id reveals which project ids exist. Reconmap stores penetration-testing engagements, so the disclosed descriptions and client records are sensitive by nature.
