CVE-2026-62673: CWE-178: Improper Handling of Case Sensitivity in getgrav grav
A case sensitivity handling flaw in Grav versions prior to 2.0.4 allows unauthenticated attackers to bypass Apache security rules by using uppercase directory or file extension variants. This can expose sensitive files such as password hashes and security configurations. The issue is fixed in Grav version 2.0.4.
AI Analysis
Technical Summary
Grav, a file-based web platform, had a vulnerability in its .htaccess and webserver-configs/htaccess.txt security rules prior to version 2.0.4. These rules omitted the Apache [NC] (no case) flag, causing directory and file-extension pattern matching to be case-sensitive. On case-insensitive filesystems, attackers could exploit this by using uppercase variants of directory names or file extensions to bypass these security rules and access sensitive files under user/accounts or user/config directories, including password hashes and security configuration files. This vulnerability is tracked as CVE-2026-62673 and is classified under CWE-178 (Improper Handling of Case Sensitivity). The issue is resolved in Grav version 2.0.4.
Potential Impact
An unauthenticated attacker can bypass security rules to access sensitive files such as password hashes and security configuration files. This exposure could lead to further compromise of the system or user accounts. The vulnerability affects confidentiality but does not require user interaction or privileges.
Mitigation Recommendations
Upgrade Grav to version 2.0.4 or later, where this issue is fixed. No other official remediation or temporary fix is documented. Patch status is confirmed fixed in 2.0.4.
