Description
The product-blocks plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'author' search of the /wopb/v1/search REST endpoint in all versions up to, and including, 4.5.8. This is due to the endpoint matching the search term against every user's e-mail address and login name for any user with the edit_posts capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to work out the e-mail addresses and login names of site users, including administrators.
