Plane · Plane · CVE-2026-104963
**Name of the Vulnerable Software and Affected Versions**
Plane versions prior to 1.4.0
**Description**
An authentication bypass allows any authenticated workspace member, including guests with limited access, to retrieve records from every project within a workspace. This occurs because the system fails to verify if the requester belongs to the specific project being accessed. An attacker can enumerate names, descriptions, sprint dates, issue counts, progress snapshots, external integration IDs, linked URLs, and member lists for cycles and modules in private projects via the following endpoints:
- '/api/workspaces/{slug}/cycles/' through WorkspaceCyclesEndpoint
- '/api/workspaces/{slug}/modules/' through WorkspaceModulesEndpoint
**Recommendations**
Update to version 1.4.0.
