 "title": "JetFormBuilder — Dynamic Blocks Form Builder <= 3.6.7 - Unauthenticated Stored Cross-Site Scripting via Preset Field Values",
 "description": "The JetFormBuilder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via form field preset values in all versions up to, and including, 3.6.7, due to field default values filled from a preset source (such as stored form records, post or user meta, or URL query variables) being treated as calculated formulas when they contain macro syntax and evaluated as JavaScript by the frontend formula engine. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute in another user's browser when that user views a page containing the affected form.",
