What is CVE-2026-104975?

The Plane project management tool had a vulnerability prior to version 1.4.0 that allowed attackers to exploit the Asset IDOR in its Spaces app. This issue arose because the EntityAssetEndpoint and AssetRestoreEndpoint could be manipulated to read, overwrite, or restore assets without proper membership checks or project_id constraints. As a result, information across multiple projects and workspaces could be accessed inappropriately. This vulnerability was mitigated in version 1.4.0.
