Summary
The WP Mail Logging WordPress plugin before 1.17.0 does not properly restrict the HTML and CSS of logged emails before rendering them in its admin log screens, allowing unauthenticated users to inject styled content and links, for example through a public contact form, that can deceive an administrator viewing the log and send their browser to an attacker-controlled page.
