Unauthenticated Local File Inclusion in Grecko <= 5.17 versions.

AnalysisAI

Unauthenticated local file inclusion in the ThemeRex Grecko WordPress theme versions 5.17 and earlier allows remote attackers to coerce the application into including arbitrary files from the server filesystem, potentially leading to sensitive file disclosure and PHP code execution where attacker-controlled content can be reached. The flaw is reachable without authentication over HTTP and was disclosed via Patchstack with no public exploit identified at time of analysis. CVSS is rated 8.1 with high attack complexity, indicating exploitation is feasible but not trivially automatable.

Technical ContextAI

Grecko is a commercial WordPress theme distributed by ThemeRex (CPE cpe:2.3:a:themerex:grecko). The root cause is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program), commonly known as PHP Remote File Inclusion / Local File Inclusion. In WordPress themes this class of bug typically arises when a PHP include()/require() statement consumes a value derived from a request parameter (often via admin-ajax.php, a theme shortcode handler, or a template-loading helper) without normalising the path or restricting it to an allowlist of expected templates. An attacker who controls that parameter can traverse the filesystem to include arbitrary local PHP files, configuration data, or - if log poisoning, session files, or uploadable content is reachable - convert disclosure into PHP code execution within the web server process.

RemediationAI

No vendor-released patched version is identified in the provided data, so administrators should consult the ThemeRex vendor portal and the Patchstack advisory (https://patchstack.com/database/wordpress/theme/grecko/vulnerability/wordpress-grecko-theme-5-17-local-file-inclusion-vulnerability) for an updated build above 5.17 and upgrade as soon as one is published. In the interim, compensating controls include placing the site behind a WAF with rules that block directory-traversal sequences (../, encoded variants, php:// and data:// wrappers) on theme endpoints, hardening PHP by setting open_basedir to the WordPress document root and disabling allow_url_include, and restricting access to admin-ajax.php and theme template-loader endpoints by IP where feasible - note these controls may break legitimate theme features that legitimately load templates dynamically, so test before enforcing. Switching off the Grecko theme entirely is the most reliable mitigation if the site can tolerate it.
