CVE-2025-67571

The WPFunnels plugin in versions up to and including 3.13.1 contains a Cross Site Scripting (XSS) vulnerability exploitable by an unauthenticated attacker.

The WPFunnels plugin versions 3.13.1 and earlier contain an unauthenticated Cross Site Scripting (XSS) vulnerability. An attacker can inject a malicious script that executes in the victim's browser.

The WPFunnels plugin for WordPress up to version 3.12.7 is vulnerable to Remote Code Execution via the 'postData' parameter. An unauthenticated attacker can write malicious data into a .log file, which is later included via include_once, allowing code execution on the server. Exploitation requires logging to be enabled and an administrator to view the polluted log file.

The WPFunnels plugin up to version 3.13.5 contains a Cross-Site Request Forgery (CSRF) vulnerability. It allows an attacker to force a logged-in user to perform unwanted actions.

The WPFunnels WordPress plugin (up to version 3.13.5) contains a missing authorization vulnerability enabling exploitation of incorrectly configured access control security levels. An unauthorized user may gain access to functions or data they should not have rights to.

The WPFunnels WordPress plugin (up to version 3.13.5) is vulnerable to a missing authorization flaw that allows exploitation of improperly configured access control security levels. The vulnerability enables unauthorized users to perform actions reserved for privileged roles.

The WPFunnels plugin for WordPress up to version 3.13.3 contains a stored XSS (Cross-site Scripting) vulnerability due to improper neutralization of input during web page generation.

Unauthenticated Insecure Direct Object References (IDOR) in WPFunnels up to version 3.13.1 allows an attacker to access resources without authorization.

The WPFunnels plugin for WordPress is vulnerable to Missing Authorization in versions up to and including 3.12.13. The plugin registers the 'wpfnl_load_payment' AJAX action for both authenticated and unauthenticated users (wp_ajax_nopriv_) and the underlying add_offer_product_to_cart() function performs no nonce verification, no capability check, and no validation that the attacker-supplied product_id is the offer product actually configured on the attacker-supplied step_id. This makes it possible for unauthenticated attackers to add arbitrary WooCommerce products to a cart at any discounted price configured on any funnel step, enabling price manipulation and revenue loss at checkout.

The WPFunnels WordPress plugin before version 3.13.0 does not perform any authorization or nonce check in one of its opt-in submission handlers, and takes notification recipients and subject from the request. This allows unauthenticated users to make the site send emails to arbitrary recipients with an arbitrary subject.
