## How to fix

- Fixed in 2.2.5

Disable Twig processing in page content by setting security.twig_content.process_enabled to false if your site uses HTTP Basic authentication and cannot upgrade immediately.

## Technical details

The Twig template sandbox in Grav 2.0.0 through 2.2.4 permits page content to access and print the request Uri object, which contains PHP_AUTH_USER and PHP_AUTH_PW from the Authorization header. An attacker with page authoring permissions can print these credentials via {{ uri }} or {{ uri.toarray.pass }} and embed the result in an inline style background-image URL to exfiltrate them to a remote server. This requires the site to use HTTP Basic authentication and either Grav 2.0.19+ with Twig processing enabled by default, or earlier versions with security.twig_content.process_enabled configured.

## Affected products

- Grav Grav 2.0.0 through 2.2.4
