Short explanation

CVE-2026-102986 in Plane versions 1.3.1 and earlier allows authenticated users to upload and delete assets in published projects without workspace or project membership verification.

Why does it matter?

This vulnerability can lead to cross-workspace file injection, storage abuse, and data loss.

What should be done?

Update Plane to version 1.4.0 or later
Follow vendor advisories

Show the technical text from the sources

Plane is an open-source project management tool. In 1.3.1 and earlier, EntityAssetEndpoint at the public project asset endpoint /api/public/assets/v2/anchor/{anchor}/ requires authentication for write operations but does not verify workspace or project membership. An authenticated user who knows a published project's public DeployBoard.anchor can create FileAsset records in that project and soft-delete existing assets by identifier, allowing cross-workspace file injection, storage abuse, and data loss. The issue is fixed in version 1.4.0.
