CVE-2025-53335
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 ThemeREX Berger berger allows PHP Local File Inclusion.This issue affects Berger: from n/a through <= 1.1.1.
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 confidenceA PHP Local File Inclusion vulnerability in ThemeREX Berger theme (versions up to 1.1.1) allows attackers to manipulate file path parameters in PHP include/require statements, potentially reading sensitive files from the server filesystem or achieving code execution.

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.
-
Confirm ThemeREX Berger theme is installedNavigate to WordPress admin > Appearance > Themes, or inspect /wp-content/themes/ directory for the 'trx_beger' or 'themerex-berger' folderAffected if The ThemeREX Berger theme folder exists in the WordPress themes directory
-
Check installed theme versionOpen the theme's style.css file in the theme folder and locate the 'Version:' header, or check theme details in WordPress admin themes panelAffected if The reported version is 1.1.1 or lower (any version up to and including 1.1.1)
-
Identify vulnerable include/require patternsSearch theme PHP files for include, include_once, require, or require_once statements that use unsanitized variables (e.g., include($_GET['param']; or require $file;)Affected if Files contain include/require statements that incorporate user-supplied input without validation (e.g., from $_GET, $_POST, or request parameters)
-
Locate the specific LFI entry pointReview PHP files in the theme's include/ or functions/ directories, looking for dynamic file inclusion where a parameter (commonly 'page', 'file', 'template', or 'path') is passed directly to include/require without sanitizationAffected if A parameter passed via URL is used in an include/require statement without sanitization (e.g., include($_GET['file']);)
-
Verify the vulnerable code is reachableTest if the identified parameter can be controlled via HTTP GET or POST requests to pages using the theme, or inspect if the code executes before any authentication checksAffected if The LFI vector is accessible without authentication or privilege escalation and the vulnerable parameter can be controlled externally
You are affected if the ThemeREX Berger theme version is 1.1.1 or lower AND your theme contains include/require statements that use unsanitized user input, which can be triggered without authentication to load arbitrary local PHP files.

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 dataReplace dynamic file inclusion with static includes, implement allowlist validation for included files, and ensure user-supplied input is never used directly in include/require statements.
