  "details": "The Webform module allows site builders to create forms, collect submissions, and configure access to forms and submission data.\n\nSite builders may also configure handlers for processing submissions, including email handlers that may include uploaded files as attachments.\n\nIn affected configurations, Webform did not sufficiently validate a managed file upload element when processing a new submission. A user with access to submit a vulnerable webform could potentially access other managed files they were not authorized to view.\n\nThis vulnerability is mitigated by the fact that a site must have a Webform with a managed file upload element and a configuration that exposes submitted files, such as allowing users to view their own webform submissions or sending uploads as email attachments.",
