## Overview

Grav is a file-based Web platform. Prior to 1.8.0-beta.27, when a user with privilege of user creation creates a new user through the Admin UI and supplies a username containing path traversal sequences (for example ..\Nijat or ../Nijat), Grav writes the account YAML file to an unintended path outside user/accounts/. The written YAML can contain account fields such as email, fullname, twofa_secret, and hashed_password. This vulnerability is fixed in 1.8.0-beta.27.

## Affected

- `grav >= 1.7.49.5, < 1.8.0`
- `grav = 1.8.0`

## Remediation

Upgrade past the affected range:

- `grav 1.8.0`
