      "value": "OpenProject is open-source, web-based project management software. Prior to 17.4.0, the GET /api/v3/relations endpoint allows any authenticated user to retrieve relations — and the subject (title) of work packages they have no permission to view — by supplying an arbitrary work package ID in the involved, fromId, or toId filter. This bypasses the Relation.visible scope due to a flawed performance optimization in RelationQuery. This vulnerability is fixed in 17.4.0."

Antes de la 17.4.0, el endpoint GET /api/v3/relations permite a cualquier usuario autenticado recuperar relaciones - y el asunto (título) de paquetes de trabajo que no tienen permiso para ver - al proporcionar un ID de paquete de trabajo arbitrario en el filtro involved, fromId o toId. Esto elude el ámbito Relation.visible debido a una optimización de rendimiento defectuosa en RelationQuery. Esta vulnerabilidad se corrigió en la 17.4.0."
