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 Sent Data vulnerability in MultiVendorX MultiVendorX dc-woocommerce-multi-vendor allows Retrieve Embedded Sensitive Data.This issue affects MultiVendorX: from n/a through <= 4.2.22.

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 MultiVendorX WordPress plugin (dc-woocommerce-multi-vendor) versions through 4.2.22 contain an information disclosure vulnerability where sensitive data is being embedded into data sent to external sources (likely API responses, logs, or network requests). This allows unauthorized retrieval of embedded sensitive information.

MitigationUpdate MultiVendorX to the latest available version. If no patched version exists, conduct a code audit to identify and remediate all locations where sensitive data (credentials, PII, payment information) is being improperly included in outgoing data transmissions.

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. Check the installed MultiVendorX plugin version
    In WordPress admin, go to Plugins > Installed Plugins and locate 'MultiVendorX' (dc-woocommerce-multi-vendor). Note the version number displayed. Alternatively, check the plugin header in /wp-content/plugins/dc-woocommerce-multi-vendor/dc-woocommerce-multi-vendor.php for the Version field.
    Affected if The installed version is lower than 4.2.23 (e.g., 4.2.22, 4.2.21, etc.)
  2. Confirm the plugin is active and vendor functionality is enabled
    Verify the MultiVendorX plugin is activated in Plugins > Installed Plugins. Then navigate to MultiVendorX settings or WooCommerce > Vendors to confirm vendor stores or capabilities are enabled and vendor data is being processed.
    Affected if The plugin is active and vendor-related features (vendor stores, product submissions, commission settings) are in use, creating conditions where data may be transmitted externally.
  3. Inspect API responses or endpoint outputs for sensitive data leakage
    Use a browser developer tool or API testing tool to capture responses from MultiVendorX endpoints (e.g., vendor dashboards, product listings, registration forms). Examine JSON responses or HTML output for unexpected exposure of credentials, user PII, payment details, or administrative tokens.
    Affected if Sensitive information (such as vendor credentials, customer data, payment information, or API keys) appears in API responses or page output that should not contain such data.
  4. Review server access and debug logs for sensitive data in outgoing requests
    Examine server access logs (often in /var/log/ or via hosting control panel) and any MultiVendorX debug logs for outgoing requests to external domains. Search for patterns containing keywords like 'password', 'token', 'key', 'credit_card', or vendor/user identifiers being sent to unknown destinations.
    Affected if Logs show sensitive data being included in requests to external servers, domains, or third-party services that were not intended to receive such information.
  5. Monitor network traffic for unauthorized data exfiltration
    Use a network monitoring tool or proxy to capture outgoing HTTP/HTTPS requests from the WordPress site. Observe requests initiated by vendor actions (e.g., vendor registration, product sync, commission calculations) and verify the payload contents.
    Affected if Network requests to external destinations contain sensitive vendor, customer, or administrative data that should remain internal or be sent only to authorized endpoints.

A user is affected if MultiVendorX version is below 4.2.23 and the plugin is actively processing vendor data that could be inadvertently included in external transmissions.

Upgrade available Upgrade to 4.2.23 or later
Fixed in 4.2.23
Interim mitigation

Update MultiVendorX to the latest available version. If no patched version exists, conduct a code audit to identify and remediate all locations where sensitive data (credentials, PII, payment information) is being improperly included in outgoing data transmissions.
