CVE-2026-22434
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 Crown Art crown-art allows PHP Local File Inclusion.This issue affects Crown Art: from n/a through <= 1.2.11.
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 confidenceCrown Art WordPress theme <= 1.2.11 contains a PHP Local File Inclusion (LFI) vulnerability allowing attackers to include arbitrary local PHP files via improper input validation. This can be chained with other techniques (e.g., log poisoning, /proc/self/environ injection) to achieve remote 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.
-
Verify Crown Art theme is installedCheck for the existence of /wp-content/themes/crown_art/ directory or search for 'Crown Art' in WordPress theme filesAffected if The theme directory exists in the WordPress installation
-
Determine the installed theme versionOpen the theme's style.css file (typically at wp-content/themes/crown_art/style.css) and locate the 'Version:' header in the CSS comment blockAffected if The version listed cannot be confirmed as patched or is within an unknown affected range
-
Identify PHP include/require statements in theme filesSearch all PHP files in the theme directory for 'include', 'require', 'include_once', or 'require_once' statements that reference variables or parameters (e.g., include($_GET['...']) or include($file))Affected if User-controlled input (GET, POST, or request parameters) flows directly into include/require statements without sanitization
-
Locate the vulnerable file path parameterExamine the identified include/require statements to find parameters that accept file paths (commonly named 'file', 'path', 'template', 'page', 'include', or similar)Affected if The parameter allows directory traversal sequences (such as ../../) or direct file paths to be passed and included
-
Test file reading capabilityIf the vulnerable parameter is identified, attempt to include a known local file (such as ../../../../wp-config.php or /etc/passwd) using a request to verify the LFI existsAffected if The server returns contents of files outside the intended theme directory
A user is affected if the Crown Art theme is installed, uses vulnerable include/require statements with unsanitized user input, and allows directory traversal to read arbitrary local 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 dataUpdate Crown Art theme to the latest version beyond 1.2.11; if no patched version exists, disable and remove the theme. Implement strict whitelist-based input validation on any file inclusion operations.
