Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for plane, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of plane for CVE-2026-30244. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
