Detailsinfo

A vulnerability, which was classified as problematic, was found in Reconmap up to 3.2.2. Affected is the function PreviewReport of the file apps/api/app/Controllers/ReportsController.cs of the component Report Preview. The manipulation of the argument id with an unknown input leads to a improper authorization vulnerability. CWE is classifying the issue as CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on confidentiality. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-77767 since 08/21/2026. The exploitability is told to be easy. It is possible to launch the attack remotely.
