Joomla Extension - balbooa.com - Unauthorized Deletion of Attachments in Balbooa Forms < 2.4.3.4 - The public removeTmpAttachment action accepts an integer attachment ID and deletes the matching database row and file. The controller verifies a Joomla session token, but the model does not bind that ID to the session that uploaded the file, the current user, the form, the upload field, or the temporary state.
