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
Missing Authorization vulnerability in Aleksandar Urošević Stock Ticker allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Stock Ticker: from n/a through 3.23.0.

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

The Stock Ticker WordPress plugin versions up to 3.23.0 contain a missing authorization vulnerability that allows attackers to exploit incorrectly configured access control security levels. This authorization bypass likely permits unauthenticated or lower-privileged users to access functionality intended for higher-privilege users due to missing capability checks or nonce validations on certain functions or AJAX endpoints.

MitigationImplement proper authorization checks (current_user_can() capability checks and nonce validation) on all sensitive functions and AJAX endpoints in the plugin to ensure users have appropriate privileges before executing restricted operations.

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. Locate the Stock Ticker plugin installation
    Check your WordPress plugins directory at wp-content/plugins/ for a folder named 'stock-ticker' or similar variant (such as 'ultimate-stock-ticker' or 'new-stock-ticker'). List all installed plugins via wp-admin/plugins.php or by inspecting the plugins folder.
    Affected if The Stock Ticker plugin is found in the plugins directory.
  2. Identify the installed plugin version
    Open the plugin's main PHP file (usually named stock-ticker.php or similar in the plugin folder) and look for the version header comment, or check the readme.txt file for the 'Stable tag' entry.
    Affected if The version is 3.23.0 or any version lower than 3.23.0.
  3. Identify plugin AJAX endpoints
    Search the plugin PHP files for 'add_action' calls registering 'wp_ajax_' or 'wp_ajax_nopriv_' hooks. These define the plugin's AJAX endpoints accessible via wp-admin/admin-ajax.php.
    Affected if AJAX endpoints without capability checks are found in the plugin.
  4. Inspect AJAX handlers for authorization checks
    Examine the callback functions registered to AJAX hooks. Search within these functions for 'current_user_can()', 'check_admin_referer()', or 'check_ajax_referer()' calls that enforce authorization.
    Affected if AJAX handlers lack capability checks or nonce validation before executing sensitive operations.
  5. Check for admin function exposure
    Review plugin PHP files for functions that perform administrative tasks (database modifications, settings changes, data imports/exports) and verify if they are reachable without proper privilege verification.
    Affected if Administrative functions can be accessed by unauthenticated users or lower-privileged roles (subscriber, contributor).

A user is affected if the Stock Ticker plugin version 3.23.0 or lower is installed and its AJAX endpoints or admin functions lack proper capability checks and nonce validation.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement proper authorization checks (current_user_can() capability checks and nonce validation) on all sensitive functions and AJAX endpoints in the plugin to ensure users have appropriate privileges before executing restricted operations.

Recommended fix Moderate confidence

Latest version after 3.23.0 (check WordPress plugin repository for current release)

  1. 1. Update the Stock Ticker plugin to the latest available version from the WordPress plugin repository
  2. 2. After updating, verify that the authorization controls are functioning correctly by testing access to restricted functionality
  3. 3. Review user roles and capabilities to ensure proper access control levels are maintained
  4. 4. Test that only authorized users can access administrative functions of the plugin
