CVE-2025-69284Network attack vector

Member identity disclosure via guest-accessible workspace endpoint

Published Jan 2, 2026 · Updated Jan 2, 2026

Improper access control in Plane before 1.2.0 allows remote authenticated users with guest access to disclose workspace member identities. The /api/workspaces/:slug/members/ endpoint returns the joined workspace's member list to guests, and each display_name exposes the email handle. A guest must already belong to the target workspace; the disclosure identifies members, including administrator email addresses.
