CVE-2026-67527

Full vulnerability record from the local CVENow database.

Description

OpenProject is open-source, web-based project management software. Prior to 17.6.0, PATCH /api/v3/work_packages/{id} accepted _links.fileLinks and allowed authenticated users with edit_work_packages but without manage_file_links to resolve Storages::FileLink records by raw id, detach or hard-delete existing FileLinks, and re-parent FileLinks from other projects to an attacker-controlled work package, exposing origin filename, origin id, and MIME type metadata. This issue is fixed in 17.6.0.

Antes de la 17.6.0, el parche /API/v3/work_packages/{id} aceptaba _links.fileLinks y permitía a usuarios autenticados con permisos de edit_work_packages pero sin manage_file_links resolver registros de Storages::FileLink por ID sin procesar, desvincular o eliminar permanentemente FileLinks existentes, y reasignar FileLinks de otros proyectos a un paquete de trabajo controlado por el atacante, exponiendo el nombre de archivo de origen, el ID de origen y los metadatos del tipo MIME. Este problema se ha solucionado en la versión 17.6.0."
