CVE-2026-28123
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 AncoraThemes Veil veil allows PHP Local File Inclusion.This issue affects Veil: from n/a through <= 1.9.
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 · moderate confidenceA Local File Inclusion (LFI) vulnerability exists in the AncoraThemes Veil PHP theme where user-controlled input is passed to include/require statements without proper validation. This allows attackers to include arbitrary PHP files from the server, potentially leading to 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.
-
Locate Veil theme installationSearch the web server's document root for directories or files belonging to the AncoraThemes Veil PHP theme. Common locations include wp-content/themes/ for WordPress or themes/ for other PHP applications.Affected if The AncoraThemes Veil theme is present on the server
-
Identify the installed versionExamine the theme's main PHP files such as style.css, functions.php, or a dedicated version.php file for a version declaration or changelog entry.Affected if The version cannot be determined or is older than the patched release
-
Search for unsafe include/require usageGrep or manually inspect the theme's PHP files for include(), require(), include_once(), or require_once() statements that incorporate $_GET, $_POST, $_REQUEST, or similar user-supplied input directly without validation or sanitization.Affected if User-controlled parameters are passed directly to include or require statements without filtering
-
Verify the vulnerable parameter is accessibleDetermine whether the parameter used in the unsafe include/require is exposed via HTTP request parameters and does not require authentication or additional access controls.Affected if The vulnerable parameter can be controlled by an external attacker through web requests
The environment is affected if the Veil theme is installed AND contains include/require statements using unsanitized user input that is externally accessible.

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 whitelist-based filtering for file paths in include/require statements, or refactor to use a predefined file mapping instead of direct user input.
