Detailsinfo

The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Plane is an open-source project management tool. Prior to 1.4.0, DuplicateAssetEndpoint fetches a source FileAsset without limiting it to the caller's workspace, allowing cross-workspace asset duplication. WorkspaceFileAssetEndpoint and the legacy FileAssetEndpoint omit workspace authorization, allowing authenticated users to read, create, modify, or delete assets in workspaces where they are not members. Separately, WorkspaceViewViewSet.retrieve lacks the authorization decorator used by its sibling actions, exposing an unauthorized workspace-view read surface. This issue is fixed in 1.4.0.
