CVE-2025-52729
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 Diza diza allows PHP Local File Inclusion.This issue affects Diza: from n/a through <= 1.3.9.
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 · high confidenceThe thembay Diza theme for a PHP application (versions up to 1.3.9) contains a Local File Inclusion (LFI) vulnerability. The application improperly controls filenames used in include/require statements, allowing attackers to manipulate path parameters to include arbitrary local PHP files. This can lead to sensitive data exposure or remote code execution if attacker-controlled files exist on the server.

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 Diza theme installation and versionSearch for theme files (typically in /wp-content/themes/diza/ or similar paths) and locate a version file such as style.css, theme.json, or a version.php that contains the theme version string. Compare this version to the affected range (up to 1.3.9).Affected if The Diza theme is installed and the version is 1.3.9 or lower.
-
Locate include/require statements using user inputSearch the theme's PHP files for patterns where $_GET, $_POST, or $_REQUEST parameters are used directly in include, require, include_once, or require_once statements without proper sanitization. Look for functions like basename(), realpath(), or allowlist validation.Affected if PHP files contain include/require statements that use unsanitized user-supplied path parameters.
-
Identify vulnerable path parametersExamine the identified include/require calls to determine which GET/POST parameters control the file path. Common parameter names may include 'file', 'path', 'page', 'template', 'load', or similar. Verify if these parameters accept directory traversal sequences like '../' or absolute paths.Affected if The path-controlling parameter accepts directory traversal or absolute file paths without validation.
-
Check PHP configuration for allow_url_includeInspect the PHP configuration file (php.ini) or create a PHP info page to check the value of the allow_url_include directive. This setting controls whether URL-aware fopen wrappers are enabled.Affected if allow_url_include is enabled (set to On), which can worsen the impact of LFI vulnerabilities.
You are affected if the Diza theme version is 1.3.9 or lower AND your theme's PHP code contains include/require statements using unsanitized user input for file paths.
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 allowlists for any parameters used in include/require statements, and use basename() or realpath() functions to sanitize file paths before inclusion. Additionally, ensure PHP's allow_url_include is disabled.
