CVE-2026-105637

Estado: AplazadaCrítica (9.6)—

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.

ExplotaciónT1210 Exploitation of Remote Serviceslateral movement85 %
Impacto principalT1565.002 Transmitted Data Manipulationimpact90 %

Acceso remoto sin privilegios elevados (PR:L) a un servicio web en red (AV:N) permite manipular referencias de activos entre proyectos, modificando metadatos y reasignando propiedades (CWE-639: Authorization Bypass). El ataque se ejecuta contra servicios remotos con credenciales básicas (Guest).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
