 "title": "Bit Form <= 3.3.1 - Unauthenticated Stored Cross-Site Scripting via SVG File Upload",
 "description": "The Bit Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via uploaded SVG files in all versions up to, and including, 3.3.1 due to an outdated bundled SVG sanitizer that could be bypassed. This makes it possible for unauthenticated attackers, submitting a form that accepts SVG uploads, to inject arbitrary web scripts in SVG files that execute whenever a user accesses the uploaded file.",
