  "details": "Grav is a file-based Web platform. Prior to 2.0.4, the Grav .htaccess and webserver-configs/htaccess.txt security rules omit the Apache [NC] flag and therefore compare sensitive directory and file-extension patterns case-sensitively. On a case-insensitive filesystem, an unauthenticated requester can use uppercase directory or extension variants to bypass the rules and retrieve files under user/accounts or user/config, including password hashes and security configuration. This issue is fixed in version 2.0.4.",
