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 confidenceA 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify the plugin is installedCheck 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
-
Identify the installed plugin versionOpen 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 pageAffected if A version is found and can be compared against any official advisories
-
Inspect form handlers for nonce verificationSearch the plugin PHP files for 'wp_nonce_field', 'wp_nonce_url', 'check_admin_referer', or 'wp_verify_nonce' function calls within form processing logicAffected if Forms that accept user input lack these nonce verification functions, indicating no CSRF protection
-
Inspect AJAX handlers for nonce verificationSearch 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 requestsAffected if AJAX actions process requests without verifying nonces, leaving them vulnerable to CSRF
-
Check for stored XSS sinksReview 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement 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.
