 "title": "Bit Form <= 3.4.0 - Unauthenticated Stored Cross-Site Scripting via URL Field",
 "description": "The Bit Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via URL field submissions in all versions up to, and including, 3.4.0. The cause is insufficient validation of URL schemes, which allowed javascript:, data: and vbscript: links to be stored and rendered as links on entry screens. This makes it possible for unauthenticated attackers to inject arbitrary scripts that execute when an administrator viewing the entry clicks the injected link.",
