CVE-2025-49886
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 WebGeniusLab Zikzag Core zikzag-core allows PHP Local File Inclusion.This issue affects Zikzag Core: from n/a through <= 1.4.5.
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 confidenceA Local File Inclusion (LFI) vulnerability in WebGeniusLab Zikzag Core allows attackers to include arbitrary local PHP files via unsanitized user input in include/require statements. This can lead to disclosure of sensitive files, source code exposure, or potentially 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 Zikzag Core installationSearch for files or directories named 'zikzag', 'Zikzag', or 'zikzag-core' in your web root, typically under wp-content/themes or wp-content/plugins. Check theme/style.css headers or plugin main files for 'Zikzag Core' or 'WebGeniusLab'.Affected if Zikzag Core by WebGeniusLab is present in your environment
-
Determine the installed versionLocate the main version file or file header for Zikzag Core. For themes, check style.css in the theme root for the 'Version:' comment. For plugins, check the main plugin PHP file header. Note the exact version number reported.Affected if The installed version falls within the affected range or is unknown/unlisted (compare your version to any published affected ranges)
-
Locate dynamic file inclusion codeSearch the Zikzag Core source code for PHP include, include_once, require, or require_once statements that use variables without basename() or realpath() sanitization. Look for patterns like 'include($variable)', 'require($_GET[...])', or similar dynamic includes.Affected if Code contains include/require statements using unsanitized variables potentially controllable via user input
-
Identify user input pathways to include statementsTrace the variables used in the vulnerable include/require statements found in step 3. Determine if they can be influenced by HTTP request parameters (GET, POST, COOKIE). Check if the application filters or validates these inputs before reaching the include statement.Affected if User-supplied input (via URL parameters, form data, or cookies) can reach the include/require statement without sanitization
Your environment is affected if Zikzag Core is installed AND the vulnerable dynamic file inclusion pattern exists with user input reaching it without sanitization.

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 and whitelisting for any parameters used in include/require statements; use basename() and realpath() functions to prevent directory traversal; consider migrating to a modern framework that avoids dynamic file inclusion.
