Description
The Themify Builder plugin for WordPress is vulnerable to Sensitive Information Exposure via the Search & Filter feature in all versions up to, and including, 7.8.2. This is due to the plugin accepting arbitrary meta keys and custom-field search targets from GET and POST parameters (such as tf_sf_meta, tf_sf_by and tf_sf_cf) instead of restricting them to the fields configured in the module. This makes it possible for unauthenticated attackers to query posts by arbitrary, including private, post meta values and use the results as an oracle to infer sensitive meta data.
