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

Deserialization of Untrusted Data vulnerability in MotoPress Timetable and Event Schedule plugin for WordPress allows Object Injection. The plugin deserializes data without proper validation, enabling attackers to inject malicious PHP objects. This could lead to arbitrary code execution depending on available gadget chains in the environment.

MitigationUpdate MotoPress Timetable and Event Schedule to the latest patched version once released. Until then, restrict access to affected endpoints and monitor for suspicious deserialization activity.

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 plugin installation and activation status
    In WordPress admin, go to Plugins > Installed Plugins and locate 'MotoPress Timetable and Event Schedule'. Check if it is installed and currently activated.
    Affected if The plugin is installed and activated, making the vulnerable code accessible.
  2. Identify installed plugin version
    Click 'View details' on the MotoPress Timetable plugin in the WordPress plugins list to display the installed version number. Alternatively, check the plugin header in its main PHP file (typically under /wp-content/plugins/motopress-timetable/).
    Affected if The installed version is within any affected version range (once published) or is an unpatched release.
  3. Locate deserialization code in plugin files
    Search the plugin directory for unserialize() function calls. Use grep or file search tools to scan PHP files in /wp-content/plugins/motopress-timetable/ for patterns like 'unserialize(', 'base64_decode(', or similar deserialization functions without prior validation.
    Affected if The plugin contains unserialize() calls that process untrusted input without proper validation.
  4. Identify the vulnerable data input point
    Review the plugin's AJAX handlers (usually in ajax.php or class files) and any public-facing forms or endpoints that accept serialized data. Check for POST/GET parameters that feed directly into unserialize() calls.
    Affected if There exists an accessible endpoint that accepts user-supplied serialized data and passes it to unserialize() without validation.
  5. Check for PHP object injection payloads in access logs
    Review web server access logs (Apache/nginx) for requests to the plugin's AJAX or form endpoints containing serialized PHP patterns (O:*, a:*, etc.) or encoded versions of such payloads.
    Affected if Suspicious serialized data patterns are observed in requests to the plugin's endpoints.

Your environment is affected if MotoPress Timetable and Event Schedule plugin is active, contains unserialize() calls processing untrusted input, and the installed version falls within the vulnerable range.
