Stock Ticker <= 3.23.2 - Cross-Site Scripting

id: CVE-2023-40208

info:
  name: Stock Ticker <= 3.23.2 - Cross-Site Scripting
  author: theamanrawat
  severity: medium
  description: |
    The Stock Ticker plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in the ajax_stockticker_load function in versions up to, and including, 3.23.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
  impact: |
    Unauthenticated attackers can inject malicious JavaScript through the class parameter in the ajax_stockticker_load function to execute attacks when users interact with malicious links.
  remediation: Fixed in version 3.23.3
