Name of the Vulnerable Software and Affected Versions MetForm WordPress plugin versions prior to 4.3.1
Description When the HubSpot Forms integration is enabled, the plugin fails to properly restrict access to a debug file created in the web root during every form submission. This allows unauthenticated attackers to read upstream API response data, which may include cookies and correlation identifiers.
Recommendations Update the plugin to version 4.3.1 or later.
