CVE-2026-105637

Plane: Cross-Project Asset Hijacking via 'ProjectBulkAssetEndpoint' (sibling of CVE-2026-46558)

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=assetids and workspace_slug=slug but does not constrain the query with projectid from the URL. A workspace Guest can provide asset UUIDs from another project in the same workspace and reassign their issueid, commentid, pageid, draftissueid, or projectid 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.
