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.

Affected: Packagist: getgrav/grav

## Summary

The default `.htaccess` shipped with Grav (and the reference `webserver-configs/htaccess.txt`) contains security rules that block direct HTTP access to sensitive file types (`.yaml`, `.yml`, `.php`, `.json`, `.twig`, etc.) under `user/` and `system/vendor/` directories. However, these rules lack the `[NC]` (No Case) flag, making them case-sensitive. On case-insensitive filesystems (Windows/NTFS, macOS/HFS+, or Linux with Docker volumes mounted from Windows/macOS), an attacker can bypass these rules by requesting files with uppercase extensions (e.g., `.YAML`, `.PHP`, `.JSON`).

## Affected Versions

- Grav 2.0.1 (latest stable as of June 2026) — confirmed - Grav 1.7.x — likely affected (same `.htaccess` rules) - All versions shipping the current `webserver-configs/htaccess.txt`

## Affected Component

File: `.htaccess` (root of Grav installation) Reference: `webserver-configs/htaccess.txt`

## Affected Rules (lines 68, 70, 72)

```apache # Line 68 — system/vendor file types RewriteRule ^(system|vendor)/(.*)\.(txt|xml|md|html|htm|shtml|shtm|json|yaml|yml|php|php2|php3|php4|php5|phar|phtml|pl|py|cgi|twig|sh|bat)$ error [F]

# Line 70 — user file types RewriteRule ^(user)/(.*)\.(txt|md|json|yaml|yml|php|php2|php3|php4|php5|phar|phtml|pl|py|cgi|twig|sh|bat)$ error [F]

# Line 72 — .md files globally RewriteRule \.md$ error [F] ```

All three rules use `[F]` without `[NC]`, making the extension match case-sensitive.

## Steps to Reproduce

1. Install Grav on a system…
