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
The js-support-ticket plugin before 2.0.6 for WordPress has CSRF.

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 js-support-ticket WordPress plugin before version 2.0.6 contains a Cross-Site Request Forgery (CSRF) vulnerability. Attackers can exploit this by tricking authenticated administrators into clicking malicious links or visiting crafted pages, causing the browser to send authenticated requests to the plugin's endpoints without the user's consent.

MitigationUpdate the js-support-ticket plugin to version 2.0.6 or later, which should include proper anti-CSRF nonce verification for all state-changing operations.

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 js-support-ticket plugin is installed
    Navigate to WordPress admin > Plugins > Installed Plugins and look for 'Js Help Desk' or 'js-support-ticket' in the plugin list
    Affected if The plugin is not found in the installed plugins list
  2. Check installed plugin version
    Click on the plugin name to view its details, or inspect the plugin header in /wp-content/plugins/js-support-ticket/js-support-ticket.php to find the 'Version' field
    Affected if The version displayed is less than 2.0.6 (for example, 2.0.5, 2.0.4, etc.)
  3. Confirm plugin is active
    In the Plugins list, verify that the plugin shows as 'Active' under the status column
    Affected if The plugin is active and the version is below 2.0.6
  4. Inspect plugin for anti-CSRF nonce implementation (optional deeper check)
    Examine the plugin's PHP files for state-changing actions (form submissions, admin actions) and check if they include wp_nonce_field() or check_admin_referer() calls
    Affected if The plugin code lacks nonce verification for sensitive operations and the version is below 2.0.6

The environment is affected if the Joomsky Js Help Desk (js-support-ticket) plugin is installed, active, and version is below 2.0.6, allowing CSRF attacks against authenticated administrators.
