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 MoreConvert Pro plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.9.14. This is due to the guest waitlist verification flow not invalidating or regenerating verification tokens when the customer email address is changed. This makes it possible for unauthenticated attackers to authenticate as existing users, including administrators, by obtaining a valid guest verification token for an attacker-controlled email, changing the same guest customer email to the target account email through the public waitlist flow, and then using the original verification link.

dbcve analysis · high confidence

The MoreConvert Pro WordPress plugin has a critical authentication bypass in its guest waitlist verification flow. The vulnerability stems from the plugin not invalidating or regenerating verification tokens when a customer email address is changed, allowing unauthenticated attackers to hijack existing user accounts including administrators by obtaining a guest verification token, changing the associated email to a target account, then using the original token to authenticate as that user.

MitigationUpdate the MoreConvert Pro plugin to a version newer than 1.9.14, or disable the plugin entirely until a patched version is available.

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 MoreConvert Pro plugin installation and version
    In WordPress admin, go to Plugins > Installed Plugins and locate MoreConvert Pro. Note the version number displayed, or check the plugin header file via file system at /wp-content/plugins/moreconvert-pro/
    Affected if The installed version is 1.9.14 or lower, or if the version cannot be determined (plugin may be outdated)
  2. Confirm guest waitlist feature is active
    Access the plugin settings page in WordPress admin (usually under MoreConvert settings or a dedicated waitlist menu item). Look for guest waitlist or waitlist verification settings. Check if the waitlist functionality is enabled.
    Affected if The guest waitlist verification feature is enabled in the plugin configuration
  3. Review existing waitlist entries for suspicious activity
    Access the plugin's waitlist management interface (typically found in WordPress admin under the plugin's menu). Examine the list of registered emails and their associated verification tokens/status. Look for unexpected email changes or tokens associated with high-privilege accounts.
    Affected if There are waitlist entries where email addresses may have been changed, or tokens exist for administrative accounts
  4. Audit WordPress user accounts for unauthorized access
    In WordPress admin, go to Users > All Users. Review user accounts, particularly administrators, for any suspicious login activity, password changes, or added capabilities. Check user metadata for any unusual waitlist-related fields.
    Affected if Any administrator account shows recent unexpected changes or the account was created/modified without legitimate admin action

A user is affected if the MoreConvert Pro plugin version is 1.9.14 or lower AND the guest waitlist feature is enabled in their WordPress environment.
