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 deserialization of untrusted data vulnerability in the WebinarIgnition WordPress plugin (versions through 3.05.0). Unsafe deserialization in PHP applications can allow remote code execution if untrusted data is passed to unserialize() without proper validation. The CVSS 8.8 score indicates high exploitability with network-accessible attack vector.

MitigationUpdate the WebinarIgnition plugin to the latest version beyond 3.05.0 when a patched release becomes available. If no patch exists, disable and remove the plugin immediately to eliminate the attack surface.

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 WebinarIgnition plugin is installed
    Navigate to WordPress admin dashboard > Plugins > Installed Plugins and look for 'WebinarIgnition' or 'Saleswonder Webinarignition' in the list. Alternatively, check the filesystem at wp-content/plugins/ for a folder named 'webinarignition' or similar.
    Affected if The plugin appears in the WordPress plugins list or filesystem.
  2. Identify installed plugin version
    In WordPress admin, click on the WebinarIgnition plugin to view details and read the version number. Or open wp-content/plugins/webinarignition/readme.txt and check the 'Stable tag' or the main plugin PHP file header for 'Version:' comment.
    Affected if The version is 3.05.0 or lower.
  3. Verify vulnerable PHP deserialization code exists
    Inspect the plugin PHP files, particularly any handling of serialized data. Look for calls to unserialize() function that process input from request parameters, POST/GET data, or database fields without sanitization. Check any API endpoints or ajax handlers within the plugin.
    Affected if Code contains unserialize() calls processing untrusted input in versions <= 3.05.0.
  4. Confirm plugin is network-accessible
    Check if the WordPress site is accessible over the network and the WebinarIgnition plugin endpoints are reachable. Test by accessing known plugin paths or submitting test requests to suspected ajax endpoints (wp-admin/admin-ajax.php?action=webinar_ignition_action).
    Affected if The plugin and its AJAX endpoints are reachable from the network.

A user is affected if WebinarIgnition plugin version 3.05.0 or lower is installed and the vulnerable unserialize() code path is accessible over the network.
