Detailsinfo

A vulnerability was found in Documize Community (unknown version). It has been classified as problematic. Affected is the function Download of the file domain/attachment/endpoint.go of the component Attachment Download. The manipulation of the argument secure 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:

Documize Community's attachment download route (domain/attachment/endpoint.go, Download function, registered via AddPublic with no auth middleware) accepts a `secure` query parameter and grants access whenever the parameter is simply non-empty (len(secureToken) > 0), without comparing it to any server-stored value. Any non-empty string, such as ?secure=x, bypasses authentication entirely and allows downloading any organization's attachments. Sibling handlers in the same file (togglePublish, delete) correctly enforce session-based authorization, confirming this is an inconsistency rather than intended design.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-71234 since 08/05/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.
