CyberRota Analysis

AI-Generated

The vulnerability in the open-source project management tool allows authenticated users to access, modify, or delete assets across workspaces without proper authorization, leading to potential data leakage and unauthorized asset manipulation. Additionally, an unauthorized read access to workspace views is exposed due to insufficient authorization checks. Organizations using versions prior to 1.4.0 should prioritize updating to the latest version to mitigate these security risks.

Original NVD Description

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.
