AI risk analysis

Summary: The flaw allows a workspace Guest to hijack assets from another project by manipulating asset UUIDs, effectively reassigning ownership and providing a presigned download URL for the hijacked file.
Exploitability: Exploitation is relatively straightforward as it requires a Guest user to provide asset UUIDs from another project, but the attacker must have access to the workspace.
Blast radius: If exploited, the real-world impact could be significant, as it allows unauthorized access to and potential download of sensitive project assets.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to version 1.4.0 or later.

NVD description

Plane is an open-source project management tool. Prior to 1.4.0, ProjectBulkAssetEndpoint.post in apps/api/plane/app/views/asset/v2.py retrieves assets using id__in=asset_ids and workspace__slug=slug but does not constrain the query with project_id from the URL. A workspace Guest can provide asset UUIDs from another project in the same workspace and reassign their issue_id, comment_id, page_id, draft_issue_id, or project_id to an entity the attacker controls. Plane then treats the attacker's project as the new owner and provides a presigned download URL for the hijacked file. This issue is fixed in 1.4.0.
