Unauthenticated Local File Inclusion in Printo <= 1.11 versions.
AnalysisAI
Unauthenticated local file inclusion in the Printo WordPress theme (versions ≤ 1.11 by ThemeRex) allows remote attackers to include arbitrary local files via a PHP file-inclusion sink (CWE-98), enabling disclosure of sensitive server-side files and potential remote code execution if attacker-controlled content can be reached on disk. No public exploit identified at time of analysis, though Patchstack has cataloged the issue and the CVSS 3.1 base score of 8.1 reflects high impact across confidentiality, integrity, and availability.
Technical ContextAI
Printo is a commercial WordPress theme distributed by ThemeRex (CPE cpe:2.3:a:themerex:printo). CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program, also known as PHP Remote File Inclusion) indicates that a PHP include(), require(), include_once(), or require_once() statement consumes a user-controllable path without adequate validation or allow-listing. In WordPress themes, this typically appears in AJAX handlers (admin-ajax.php / admin-post.php with nopriv_ actions), template-loader shortcodes, or shortcode/loader endpoints that accept a template, view, or page parameter. Because the affected sink is reachable without authentication, the request can be issued by any anonymous HTTP client against the WordPress front-end.
RemediationAI
No vendor-released patch identified at time of analysis; the Patchstack advisory (https://patchstack.com/database/wordpress/theme/printo/vulnerability/wordpress-printo-theme-1-11-local-file-inclusion-vulnerability) does not list a fixed Printo release, so site owners should contact ThemeRex for an updated build or, if none is forthcoming, deactivate and replace the Printo theme. Compensating controls while waiting for a fix: deploy a WordPress WAF (Patchstack, Wordfence, or equivalent) with a virtual-patch rule for this CVE; block requests to the vulnerable theme endpoint at the reverse proxy (typically wp-content/themes/printo/* PHP files that are not normal template entry points, plus suspicious admin-ajax.php actions originating from the theme) - trade-off is that legitimate theme features invoking that endpoint will break; enforce open_basedir / disable_functions in php.ini to restrict which files PHP can include and to neutralize follow-on RCE primitives - trade-off is potential breakage of legitimate plugins; restrict outbound network egress from the web server to limit data exfiltration if file disclosure occurs.
