What it is

Grav from 2.0.0 before 2.2.5 contains an information disclosure vulnerability that allows page authors to capture visitors' HTTP Basic credentials through Twig page content. Authors can print the request Uri object, which embeds PHP_AUTH_USER and PHP_AUTH_PW, inside an inline style background image to exfiltrate administrators' credentials to an external host.
