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

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

This is a PHP Object Injection vulnerability in the Pagaleve WooCommerce plugin (wc-pagaleve). The plugin deserializes untrusted data without proper validation, allowing attackers to inject malicious PHP objects. This can potentially lead to remote code execution, file deletion, or SQL injection depending on available magic methods in the application context.

MitigationUpdate the Pagaleve plugin to a version beyond 1.6.9 as soon as a patched release is available. If no patch is available, disable the plugin until a fix is released.

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. Check if Pagaleve plugin is installed
    Navigate to WordPress admin > Plugins, or inspect the /wp-content/plugins/ directory for a folder named 'wc-pagaleve' or similar Pagaleve-related plugin
    Affected if The plugin is not installed
  2. Verify the installed version
    Check the plugin header in the main PHP file (usually wc-pagaleve.php) or view the version on the WordPress plugins page. Compare against the affected range: version 1.6.9 and below
    Affected if Version is 1.6.9 or lower
  3. Search for unsafe unserialize calls
    Use grep or a file search to look for 'unserialize' within the plugin directory. Focus on calls that process input from $_GET, $_POST, $_COOKIE, request parameters, or database values
    Affected if Any unserialize() calls are found that handle untrusted user input
  4. Identify exposed entry points
    Examine the plugin source code for AJAX action handlers, REST API routes, webhook callbacks, or form processing code that receive external data and pass it to unserialize()
    Affected if Exposed endpoints accept and deserialize data from untrusted sources

The environment is affected if the Pagaleve wc-pagaleve plugin version 1.6.9 or lower is installed and contains unsafe unserialize() calls that process untrusted input from external sources.
