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 WP Email Debug plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the WPMDBUG_handle_settings() function in versions 1.0 to 1.1.0. This makes it possible for unauthenticated attackers to enable debugging and send all emails to an attacker controlled address and then trigger a password reset for an administrator to gain access to an administrator account.

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 WP Email Debug plugin for WordPress versions 1.0 to 1.1.0 lacks a capability check on the WPMDBUG_handle_settings() function, allowing unauthenticated attackers to modify plugin settings. Attackers can enable debugging and redirect all outgoing emails to an attacker-controlled address, then trigger a password reset for an administrator and intercept the reset token to gain administrative access.

MitigationUpdate WP Email Debug to version 1.1.1 or later which adds proper capability checks; alternatively, disable the plugin until patched.

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 WP Email Debug plugin is installed
    Log in to WordPress admin and navigate to Plugins > Installed Plugins, or check the /wp-content/plugins/ directory for the wp-email-debug folder
    Affected if The plugin is present in the plugins directory or listed in the WordPress admin plugins list
  2. Determine the installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins and locate WP Email Debug; the version number is displayed under the plugin name. Alternatively, check the main plugin file (wp-email-debug.php) for the 'Version' header comment
    Affected if The version is 1.0, 1.1.0, or any version between 1.0 and 1.1.0 inclusive
  3. Confirm the plugin is active
    In WordPress admin > Plugins > Instored Plugins, check if WP Email Debug shows 'Active' status under the plugin name
    Affected if The plugin is active; inactive plugins do not expose the vulnerable function to unauthenticated requests
  4. Inspect email forwarding settings for unknown destinations
    Navigate to the plugin settings page (usually under Settings > Email Debug or similar) and examine any fields related to email forwarding, redirection, or debug email addresses. Check for unfamiliar or suspicious email addresses that were not configured by legitimate administrators
    Affected if Email forwarding is enabled and directed to an address you do not recognize or did not configure, indicating possible exploitation

You are affected if the WP Email Debug plugin is installed, active, and running at version 1.1.0 or earlier, or if you discover unauthorized email forwarding configurations in the plugin settings.

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

Update WP Email Debug to version 1.1.1 or later which adds proper capability checks; alternatively, disable the plugin until patched.

Recommended fix Moderate confidence

Version 1.1.1 or later

  1. 1. Backup your WordPress database and files before making any changes.
  2. 2. Navigate to Plugins > Installed Plugins in the WordPress admin dashboard.
  3. 3. Locate the 'WP Email Debug' plugin in the list.
  4. 4. If an update is available, click 'Update Now' to upgrade to version 1.1.1 or later.
  5. 5. Alternatively, you can manually download the fixed version from the WordPress plugin repository and upload it via Plugins > Add New > Upload Plugin.
