 "title": "WeForms <= 1.6.28 - Unauthenticated Insecure Direct Object Reference to Arbitrary Attachment Deletion via Upload Field Values",
 "description": "The weForms plugin for WordPress is vulnerable to Insecure Direct Object Reference via the image and file upload field values of a front-end form submission in all versions up to, and including, 1.6.28, due to missing validation on a user controlled key. Attachment IDs submitted in an upload field are saved with the entry without checking that the submitter uploaded them, and every stored ID is force-deleted when the entry is permanently deleted. This makes it possible for unauthenticated attackers to add any media library attachment to a form entry. That attachment and its file are permanently deleted when an administrator permanently deletes the entry.",
