Summary

Plane is Vulnerable to Unauthenticated Workspace Member Information Disclosure

Details

Executive Summary

A security vulnerability exists in the Plane project management platform that allows unauthenticated attackers to enumerate workspace members and extract sensitive information including email addresses, user roles, and internal identifiers. The vulnerability stems from Django REST Framework permission classes being incorrectly configured to allow anonymous access to protected endpoints.

This vulnerability enables attackers to:

Enumerate all members of any workspace without authentication
Extract user email addresses and personally identifiable information (PII)
Identify administrative accounts for targeted attacks
Map organizational structure and user roles
Conduct reconnaissance for social engineering attacks

Affected Endpoints:

GET /api/public/workspaces/{workspace_slug}/members/
GET /api/public/workspaces/{workspace_slug}/projects/{project_id}/members/

A fix is available at https://github.com/makeplane/plane/releases/tag/v1.2.3.

Severity

7.5 (High)
