CVE-2025-68540
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in thembay Fana fana allows PHP Local File Inclusion.This issue affects Fana: from n/a through <= 1.1.35.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe thembay Fana theme contains a PHP Local File Inclusion (LFI) vulnerability where user-supplied input is used in include/require statements without proper validation. This allows attackers to read sensitive local files or potentially achieve code execution if they can control the included files.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Fana theme versionLocate the theme's version file (typically version.php, style.css with version comment, or composer.json in the theme directory) and note the version numberAffected if The installed version is lower than the patched version referenced in CVE-2025-68540 advisories
-
Find PHP files using include/require with dynamic inputSearch the theme directory for PHP files containing 'include(' or 'require(' combined with $_GET, $_POST, or $_REQUEST parameters (e.g., grep -r 'include.*\$_' or manually inspect PHP files in the theme root and subdirectories)Affected if User-supplied parameters are used directly in include/require statements without sanitization (e.g., include($_GET['file']);)
-
Identify the vulnerable parameter nameExamine the identified include/require statements to determine which GET/POST parameter controls the file path (common names include 'file', 'page', 'template', 'path', or 'lang')Affected if A parameter accepting file paths is processed without validation (e.g., allowlist or realpath() checks)
-
Check if the file inclusion functionality is accessibleDetermine if the vulnerable PHP file can be accessed via HTTP/HTTPS requests (check web server routing, .htaccess rules, or whether the file requires admin authentication)Affected if The vulnerable code path is reachable without authentication or can be triggered by low-privilege users
-
Test for LFI via the identified parameterIf authorized in your own environment, attempt to include a safe test file (e.g., ?param=../../../../etc/passwd or ?param=config.php) to confirm the LFI behavior existsAffected if The application returns contents of files outside the intended directory or configuration files
You are affected if the Fana theme is installed with a version prior to the CVE-2025-68540 patch AND the vulnerable include/require pattern exists in accessible PHP files using unsanitized user input.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation using an allowlist approach for file inclusion parameters, and avoid using user input directly in include/require statements. If the affected version cannot be updated, consider disabling PHP execution in accessible directories and deploying a WAF rule to block traversal patterns.
