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
Insertion of Sensitive Information into Log File vulnerability in Paid Memberships Pro Paid Memberships Pro – Mailchimp Add On pmpro-mailchimp.This issue affects Paid Memberships Pro – Mailchimp Add On: from n/a through 2.3.4.

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 Paid Memberships Pro Mailchimp Add-On plugin (pmpro-mailchimp) writes sensitive information to log files. Based on the nature of the plugin, this likely includes Mailchimp API keys, email addresses, or membership-related personal data that gets exposed in plaintext log files accessible to attackers or unauthorized administrators.

MitigationAudit all log statements in the plugin to identify and remove or sanitize sensitive fields (API keys, email addresses, personal data) before logging. Purge or secure any existing log files that may contain exposed sensitive information.

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 pmpro-mailchimp plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'PMPro Mailchimp' or check the plugin files in /wp-content/plugins/pmpro-mailchimp/ directory
    Affected if The plugin is installed and active
  2. Check plugin version against affected range
    Look in the plugin header comment in the main PHP file (usually pmpro-mailchimp.php) for the 'Version' field, or check the WordPress plugin repository if installed from there
    Affected if Version is unknown or unpatched - the vulnerability exists in the plugin code regardless of version since it relates to improper logging of sensitive data
  3. Verify if WordPress debug logging is enabled
    Check wp-config.php for define( 'WP_DEBUG', true ); and define( 'WP_DEBUG_LOG', true ); settings
    Affected if Debug logging is enabled and writes to /wp-content/debug.log
  4. Locate plugin-specific log files
    Look for log files in /wp-content/uploads/pmpro-mailchimp/ or /wp-content/pmpro-mailchimp-logs/ directories, and check the plugin settings page for custom log file paths
    Affected if Log files exist in these or similar directories
  5. Inspect log files for exposed sensitive data
    Open any found log files and search for strings matching API key patterns (typically 32+ character alphanumeric strings), email addresses (@ symbol), or membership/personal data
    Affected if Log files contain plaintext Mailchimp API keys, email addresses, or member personal information

A user is affected if the pmpro-mailchimp plugin is installed with logging enabled and sensitive data is present in plaintext in any log files.
