Vulnerability Title
Grav Exposes Password Hashes Leading to privilege escalation
Source: CVE Program / CVE List V5
Vulnerability Description
Grav is a file-based Web platform. Prior to 1.8.0-beta.27, users with read access on the user account management section of the admin panel can view the password hashes of all users, including the admin user. This exposure can potentially lead to privilege escalation if an attacker can crack these password hashes. This vulnerability is fixed in 1.8.0-beta.27.
