CVE-2026-52779
Full vulnerability record from the local CVENow database.
Description
OpenProject is open-source, web-based project management software. Prior to 17.3.3 and 17.4.1, a cross-project IDOR / authorization context confusion in the Calendar and Team Planner modules allows a user with management permissions in one project to delete public Calendar or Team Planner Queries from another project where they do not have the corresponding management permissions. Both modules authorize the request against the project identified by :project_id in the URL, but the actual Query object is loaded later by :id from Query.visible(current_user) without verifying that the loaded Query belongs to the authorized project. As a result, an attacker can use permissions from Project A to delete shared/public Calendar or Team Planner views from Project B, causing integrity impact and limited availability impact for users relying on those shared views. This vulnerability is fixed in 17.3.3 and 17.4.1.

"value": "OpenProject es un software de gestión de proyectos de código abierto y basado en la web. Antes de las versiones 17.3.3 y 17.4.1, una confusión de contexto de IDOR / autorización entre proyectos en los módulos de Calendario y Planificador de Equipo permite a un usuario con permisos de gestión en un proyecto eliminar Consultas públicas de Calendario o Planificador de Equipo de otro proyecto donde no tienen los permisos de gestión correspondientes. Ambos módulos autorizan la solicitud contra el proyecto identificado por :project_id en la URL, pero el objeto Consulta real se carga más tarde por :id desde Query.visible(current_user) sin verificar que la Consulta cargada pertenece al proyecto autorizado. Como resultado, un atacante puede usar permisos del Proyecto A para eliminar vistas compartidas/públicas de Calendario o Planificador de Equipo del Proyecto B, causando un impacto en la integridad y un impacto limitado en la disponibilidad para los usuarios que dependen de esas vistas compartidas. Esta vulnerabilidad se corrige en las versiones 17.3.3 y 17.4.1."
