Description
The Responder plugin for WordPress is vulnerable to Sensitive Information Exposure via the Responder Debug log (responder_debug custom post type) in all versions up to, and including, 4.4.4 due to the post type being registered with the default 'post' capability type and meta-capability mapping instead of administrator-only capabilities. This makes it possible for authenticated attackers, with Contributor-level access and above, to list debug entries whose titles reveal submitted lead identities, and for Editor-level users to open entries containing leads' names, email addresses, phone numbers and API responses. Exploitation requires the plugin's debug logging to be enabled.
