What the vulnerability does
01Description
The WebP Express plugin for WordPress is vulnerable to information exposure via config files in all versions up to, and including, 0.25.9. This is due to the plugin not properly randomizing the name of the config file to prevent direct access on NGINX. This makes it possible for unauthenticated attackers to extract configuration data.
