Grav is a file-based Web platform. Prior to version 1.7.46, a low privilege user account with page edit privilege can read any server files using Twig Syntax. This includes Grav user account files - `/grav/user/accounts/*.yaml`. This file stores hashed user password, 2FA secret, and the password reset token. This can allow an adversary to compromise any registered account and read any file in the web server by resetting a password for a user to get access to the password reset token from the file or by cracking the hashed password. A low privileged user may also perform a full account takeover of other registered users including Administrators. Version 1.7.46 contains a patch.

- GHSA-f8v5-jmfh-pr69Grav Vulnerable to Arbitrary File Read to Account Takeover2024-05-15ghsa · osvUS
### Summary A low privilege user account with page edit privilege can read any server files using Twig Syntax. This includes Grav user account files - /grav/user/accounts/*.yaml. This file stores hashed user password, 2FA secret, and the password reset token. This can allow an adversary to compromise any registered account by resetting a password for a user to get access to the password reset token from the file or by cracking the hashed password. ### Proof Of Concept `{{ read_file('/var/www/html/grav/user/accounts/riri.yaml') }}` Use the above Twig template syntax in a page and observe that the administrator riri's authentication details are exposed accessible by any unauthenticated user.  As an additional proof of concept for reading system files, observe the `/etc/passwd` file read using the following Twig syntax: `{{ read_file('/etc/passwd') }}`  ### Impact This can allow a low privileged user to perform a full account takeover of other registered users including Adminsitrators. This can also allow an adversary to read any file in the web server.
