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.

Deserialization of Untrusted Data vulnerability in emarket-design WP Ticket Customer Service Software & Support Ticket System wp-ticket allows Object Injection.This issue affects WP Ticket Customer Service Software & Support Ticket System: from n/a through <= 6.0.2.

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

A deserialization vulnerability in the WP Ticket Customer Service Software & Support Ticket System plugin (versions <= 6.0.2) allows attackers to inject malicious PHP objects by supplying untrusted serialized data. This PHP Object Injection can potentially lead to remote code execution depending on available gadgets in the application and WordPress environment.

MitigationUpdate to the latest patched version of the wp-ticket plugin. If no update is available, disable the plugin until a fix is released. Review the plugin's AJAX endpoints and request handlers for insecure use of unserialize() on user-supplied input.

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. Confirm WP Ticket plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for a folder named 'wp-ticket' or search for 'WP Ticket Customer Service Software' in the WordPress admin plugin list
    Affected if The plugin folder or listing exists in the WordPress installation
  2. Identify installed plugin version
    Open the main plugin file (wp-content/plugins/wp-ticket/wp-ticket.php or similar) and locate the version comment/header, or check the WordPress plugin admin page for the installed version number
    Affected if The version number is 6.0.2 or lower
  3. Locate plugin AJAX endpoints
    Search the plugin directory for files containing 'add_action( 'wp_ajax_' or 'wp_ajax_nopriv_' to identify AJAX request handlers
    Affected if AJAX handlers exist that process user-supplied data
  4. Check for insecure unserialize usage
    Search the plugin PHP files for the string 'unserialize(' and examine whether it processes input from $_POST, $_GET, or $_REQUEST superglobals without sanitization
    Affected if Code uses unserialize() on raw user input from request parameters

If the plugin version is 6.0.2 or lower AND the plugin contains AJAX handlers that call unserialize() on user-supplied input, the environment is vulnerable to CVE-2025-53584.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to the latest patched version of the wp-ticket plugin. If no update is available, disable the plugin until a fix is released. Review the plugin's AJAX endpoints and request handlers for insecure use of unserialize() on user-supplied input.
