NVD · unedited
Deserialization of Untrusted Data vulnerability in CoinPayments CoinPayments.net Payment Gateway for WooCommerce coinpayments-payment-gateway-for-woocommerce allows Object Injection.This issue affects CoinPayments.net Payment Gateway for WooCommerce: from n/a through <= 1.0.17.

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 CoinPayments.net Payment Gateway for WooCommerce plugin versions up to 1.0.17 contains a PHP Object Injection vulnerability via deserialization of untrusted data. An attacker can potentially exploit this by injecting malicious PHP objects into the deserialization process, which may lead to remote code execution if suitable magic methods exist in the plugin or associated libraries.

MitigationUpdate to the latest version of the CoinPayments.net Payment Gateway for WooCommerce plugin when available. If no patch exists, disable the plugin until a fix is released. Alternatively, implement input validation and use json_encode/JSON format instead of PHP serialization for any data handling.

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 CoinPayments.net plugin is installed
    Log into WordPress admin panel, navigate to Plugins > Installed Plugins, and look for 'CoinPayments.net Payment Gateway for WooCommerce' in the list. Note the version number displayed.
    Affected if The plugin is installed and the version is 1.0.17 or lower
  2. Check plugin version via filesystem
    If admin access is unavailable, access the server via SFTP or shell and locate the plugin directory (typically wp-content/plugins/coinpayments-net-payment-gateway-for-woocommerce). Open the main plugin PHP file (often named coinpayments.php or similar) and find the Version header in the plugin comment block.
    Affected if The Version field reads 1.0.17 or below
  3. Search for unsafe deserialization in plugin code
    Using grep or a file search tool, search the plugin directory for calls to PHP unserialize() function. Examine any files containing unserialize() to determine if they process data from external sources such as $_POST, $_GET, $_COOKIE, or HTTP request bodies.
    Affected if The plugin code contains unserialize() calls that process input from untrusted sources such as payment callbacks, API responses, or user-submitted form data
  4. Identify payment callback endpoints
    Review the plugin for WordPress hooks or REST API routes that handle incoming requests from CoinPayments.net servers. Check for any action hooks (wp_ajax_, wp_hooks) or rewrite rules that accept serialized data from remote payment notifications.
    Affected if The plugin receives and deserializes data from payment notification webhooks or callback URLs without prior sanitization

You are affected if the CoinPayments.net Payment Gateway for WooCommerce plugin version is 1.0.17 or lower AND the plugin code contains unserialize() calls that process external input from payment callbacks or API responses.
