Description

Plane version 0.7.1 allows an unauthenticated attacker to view all stored server files of all users.

Vulnerability

In the application users can change the photo of their avatar and upload different types of files of different extensions which are all stored in the same folder and there is no restriction. Any unauthenticated person can access and download the resources. Knowing that Plane is created to create issues on projects and manage them, this is critical, because if bugs are reported on an application, an attacker can obtain the evidence and files of the same issue.

Exploit

Evidence of exploitation

By accessing the /uploads/ directory you can see all the files stored on the server.
