Prior to 2.18.19 and from 2.19.0-alpha3 until 2.19.5-beta5, ProjectMiddleware and GetProjectOrGlobalRoleBySlug allow a project manager to use POST /api/project/{id}/roles to create a custom manager role with permission bitmask 15, overriding the built-in manager permissions and granting CanUpdateProject and CanManageProjectUsers owner capabilities. This issue is fixed in versions 2.18.19 and 2.19.5-beta5."

Antes de la versión 2.18.19 y desde la 2.19.0-alpha3 hasta la 2.19.5-beta5, ProjectMiddleware y GetProjectOrGlobalRoleBySlug permiten a un gestor de proyectos usar POST /API/project/{id}/roles para crear un rol de gestor personalizado con una máscara de bits de permisos 15, anulando los permisos de gestor integrados y otorgando las capacidades de propietario CanUpdateProject y CanManageProjectUsers. Este problema está solucionado en las versiones 2.18.19 y 2.19.5-beta5."
