CVE-2026-102986

Plane: Any Authenticated User Can Upload and Delete Assets in Any Published Project via /api/public/assets/v2/anchor/{anchor}/

Published Oct 14, 2026 CVSS 3.1 · 8.1 High EPSS < 1% KEV · Not listed
Description
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.
