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
WordPress TheCartPress 1.5.3.6 contains an unauthenticated privilege escalation vulnerability that allows attackers to create administrator accounts by submitting crafted requests to the AJAX handler. Attackers can send POST requests to the tcp_register_and_login_ajax action with tcp_role set to administrator to gain full administrative access without authentication.

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 · high confidence

The TheCartPress WordPress plugin versions 1.5.3.6 and below contains an unauthenticated privilege escalation vulnerability in its AJAX handler. Attackers can send POST requests to the tcp_register_and_login_ajax action with the tcp_role parameter set to 'administrator' to create a new administrator account without any authentication, gaining full administrative access to the WordPress site.

MitigationImmediately update TheCartPress to the latest patched version or remove the plugin if no patch is available. Audit the WordPress installation for unauthorized administrator accounts created by attackers and remove them. Consider a full compromise assessment given the critical severity and complete administrative access gained.

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 TheCartPress plugin is installed
    Navigate to WordPress admin dashboard > Plugins and look for TheCartPress in the list of installed plugins
    Affected if TheCartPress appears in the installed plugins list
  2. Check installed version of TheCartPress
    In the Plugins list, look at the version displayed beneath TheCartPress or check the plugin's main PHP file for the version constant
    Affected if The version listed is 1.5.3.6 or lower
  3. Inspect the tcp_register_and_login_ajax AJAX endpoint
    Check plugin source code for the tcp_register_and_login_ajax action handler and verify if the tcp_role parameter is validated before creating the user
    Affected if The code accepts the tcp_role parameter without proper authorization validation and allows setting it to 'administrator'
  4. Review user accounts for unauthorized administrators
    Go to WordPress Users panel and examine all accounts with Administrator role, focusing on any created recently or with unfamiliar email addresses
    Affected if There are administrator accounts that were not created by legitimate site administrators
  5. Check server access logs for POST requests to tcp_register_and_login_ajax
    Search HTTP access logs for POST requests containing 'tcp_register_and_login_ajax' and inspect for suspicious payloads with tcp_role=administrator
    Affected if Such requests exist from unknown IP addresses, especially in bulk or with unusual timing

You are affected if TheCartPress plugin version 1.5.3.6 or below is installed and the tcp_register_and_login_ajax endpoint is exposed, or if unauthorized administrator accounts exist on the site.

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

Immediately update TheCartPress to the latest patched version or remove the plugin if no patch is available. Audit the WordPress installation for unauthorized administrator accounts created by attackers and remove them. Consider a full compromise assessment given the critical severity and complete administrative access gained.

Recommended fix Moderate confidence

Latest available version of TheCartPress from wordpress.org (check plugin repository for post-1.5.3.6 release)

  1. 1. Check the current version of TheCartPress plugin installed on your WordPress site.
  2. 2. If the installed version is 1.5.3.6 or earlier, navigate to Plugins > Installed Plugins in the WordPress admin dashboard.
  3. 3. Locate TheCartPress in the plugin list and check for available updates.
  4. 4. If an update is available, click 'Update Now' to install the latest version.
  5. 5. After updating, verify the fix by attempting a test registration with tcp_role parameter to confirm the vulnerability is patched.
  6. 6. If no update is available from the WordPress plugin repository, consider: (a) contacting the plugin developer directly for a patched version, (b) disabling the plugin if not essential, or (c) implementing a web application firewall (WAF) rule to block requests with the tcp_role parameter.
