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 · high confidence

A Cross-Site Request Forgery (CSRF) vulnerability in the WordPress plugin 'my-auctions-allegro-free-edition' allows attackers to inject malicious JavaScript through stored XSS. The plugin fails to validate anti-CSRF tokens (nonces) on forms and AJAX actions, enabling attackers to craft malicious requests that execute in other users' browsers.

MitigationImplement WordPress nonce verification on all form submissions and AJAX endpoints in the plugin, and add CSRF tokens to vulnerable forms to prevent unauthorized request execution.

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. Verify the plugin is installed
    Check the WordPress plugins directory for 'my-auctions-allegro-free-edition' folder, typically at wp-content/plugins/my-auctions-allegro-free-edition/
    Affected if The plugin folder exists in the WordPress installation
  2. Identify the installed plugin version
    Open the main plugin PHP file (usually my-auctions-allegro-free-edition.php) and locate the Version header in the plugin comment block, or check the plugin metadata via WordPress admin plugins page
    Affected if A version is found and can be compared against any official advisories
  3. Inspect form handlers for nonce verification
    Search the plugin PHP files for 'wp_nonce_field', 'wp_nonce_url', 'check_admin_referer', or 'wp_verify_nonce' function calls within form processing logic
    Affected if Forms that accept user input lack these nonce verification functions, indicating no CSRF protection
  4. Inspect AJAX handlers for nonce verification
    Search for add_action calls registering AJAX endpoints (like 'wp_ajax_') and verify they include nonce checking via 'check_ajax_referer' or 'wp_verify_nonce' before processing requests
    Affected if AJAX actions process requests without verifying nonces, leaving them vulnerable to CSRF
  5. Check for stored XSS sinks
    Review code that saves user input to the database (insert/update SQL queries, update_option, etc.) and outputs it without sanitization (esc_html, esc_attr, sanitize_text_field)
    Affected if User-supplied data is stored and displayed without proper sanitization, allowing stored XSS to be triggered via CSRF

If the plugin is installed and its forms or AJAX endpoints lack nonce verification, the environment is affected by this CSRF vulnerability that can lead to stored XSS.
