Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Aleksandar Urošević Stock Ticker allows Stored XSS.This issue affects Stock Ticker: from n/a through 3.23.4.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Stored Cross-site Scripting (XSS) vulnerability in the Stock Ticker plugin allows attackers to inject malicious JavaScript code through unsanitized user input (likely stock symbol or ticker data). The malicious payload is stored in the database and executes when other users view affected pages.

MitigationUpdate Stock Ticker to the latest version if available, or implement output encoding/sanitization on all user input fields using appropriate functions (such as esc_html, esc_attr, or wp_kses in WordPress context).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Stock Ticker plugin is installed
    Check WordPress plugins directory or wp-admin/plugins.php for the 'Urosevic Stock Ticker' plugin
    Affected if Plugin is present in the WordPress installation
  2. Identify installed plugin version
    View plugin details in WordPress admin (Plugins > Installed Plugins > Stock Ticker) or inspect plugin header in the main PHP file (typically wp-content/plugins/stock-ticker/*.php) for the 'Version' field
    Affected if Version number is 3.23.4 or lower
  3. Locate user input fields for stock symbols
    Identify pages or admin settings where stock symbols/ticker data can be added or modified - check plugin settings pages and any frontend forms that accept stock ticker input
    Affected if User input fields accept stock symbols without visible sanitization indicators
  4. Inspect stored ticker data for suspicious content
    Examine the database tables where plugin stores stock data (look for tables containing 'stock', 'ticker', or custom post meta associated with the plugin). Search for patterns like <script, javascript:, onload=, onerror=, or other XSS payloads in stored values
    Affected if Database contains unsanitized JavaScript or HTML tags in stock symbol/ticker fields
  5. Check frontend output for unescaped content
    View pages displaying stock ticker information in a browser. Use browser developer tools (F12) or view page source to examine if stock symbol data appears as raw text or is being rendered as HTML/script
    Affected if Stock ticker data renders as executable HTML or JavaScript rather than escaped text

A user is affected if the Stock Ticker plugin version is 3.23.4 or lower AND user-supplied stock symbols are stored and rendered without proper output encoding.

dbcve · scoped
Upgrade available Upgrade to a release after 3.23.4
Interim mitigation

Update Stock Ticker to the latest version if available, or implement output encoding/sanitization on all user input fields using appropriate functions (such as esc_html, esc_attr, or wp_kses in WordPress context).

Recommended fix Moderate confidence

Stock Ticker version 3.23.5 or later (latest available version)

  1. 1. Update Stock Ticker plugin to the latest available version from the WordPress plugin repository or the vendor's official source.
  2. 2. After updating, verify that the plugin is functioning correctly on your site.
  3. 3. Test that the previously vulnerable functionality (stock ticker display) works as expected with the new version.
  4. 4. Consider running a security scan of your WordPress site to confirm no malicious scripts were injected during the time the vulnerability was present.
