NVD · unedited
Cross-Site Request Forgery (CSRF) vulnerability in Aaron Forgue Amazon Showcase WordPress Plugin amazon-showcase-wordpress-widget allows Stored XSS.This issue affects Amazon Showcase WordPress Plugin: from n/a through <= 2.2.

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

CSRF vulnerability in the Amazon Showcase WordPress plugin enables attackers to inject malicious scripts via stored XSS. Attackers can craft requests that trick authenticated administrators into executing unintended actions, with the injected payload persisting and executing for all users viewing the affected content.

MitigationImplement anti-CSRF nonce verification on all form submissions and AJAX endpoints, apply proper input validation and sanitization before database storage, and ensure all output is escaped when rendered.

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. Identify if Amazon Showcase plugin is installed
    Access WordPress admin panel under Plugins > Installed Plugins, or inspect the /wp-content/plugins/ directory for an 'amazon-showcase' folder. Check the plugin header for version information.
    Affected if The Amazon Showcase plugin is installed and no security patch has been applied to address CVE-2025-39431
  2. Verify form submissions have anti-CSRF nonce protection
    Examine the plugin PHP source code for form handlers. Search for wp_nonce_field, check_admin_referer, or wp_verify_nonce function calls on POST/GET requests that handle plugin settings or content submissions.
    Affected if Form handling code lacks nonce verification logic, allowing attackers to craft malicious requests on behalf of authenticated administrators
  3. Verify AJAX endpoints have anti-CSRF nonce protection
    Inspect the plugin AJAX handlers (wp_ajax_ and wp_ajax_nopriv_ hooks). Check if each handler includes nonce verification before processing requests.
    Affected if AJAX endpoints do not validate nonces, permitting unauthorized cross-site request forgery attacks
  4. Confirm input is sanitized before database storage
    Review code that processes and stores user-supplied data. Look for sanitization functions such as sanitize_text_field, esc_attr, or wp_kses applied to input before INSERT/UPDATE operations.
    Affected if User input is stored in the database without sanitization, allowing malicious scripts to persist
  5. Confirm output is escaped when rendered
    Inspect template files and output functions that display stored data. Verify that echoed content uses escaping functions like esc_html, esc_attr, or wp_kses when rendering to users.
    Affected if Stored content is rendered without proper output escaping, causing the injected XSS payload to execute in user browsers

Users are affected if the Amazon Showcase plugin is installed and its form handlers, AJAX endpoints, input processing, or output rendering lack the anti-CSRF nonce verification and proper sanitization/escaping required to prevent stored XSS exploitation.

Mitigation

Implement anti-CSRF nonce verification on all form submissions and AJAX endpoints, apply proper input validation and sanitization before database storage, and ensure all output is escaped when rendered.

Recommended fix Moderate confidence

latest available version after 2.2 (check WordPress plugin repository for current stable release)

  1. 1. Log in to the WordPress admin dashboard
  2. 2. Navigate to Plugins > Installed Plugins
  3. 3. Locate the 'Amazon Showcase' plugin (also known as 'amazon-showcase-wordpress-widget')
  4. 4. Check the current installed version number
  5. 5. Navigate to Plugins > Add New > Upload Plugin or check the WordPress plugin repository for the latest version
  6. 6. Update the plugin to the latest available version that addresses the CSRF vulnerability
  7. 7. Verify the update was successful by confirming the new version number
  8. 8. Test the plugin functionality to ensure it works correctly after the update
