Publication date: 2026-09-25

Last updated on: 2026-09-25

Assigner: Wordfence

Description
The WPForms – AI Form Builder for WordPress – Contact Forms, Payment Forms, Survey Form, Quiz & More plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'page_title' POST Parameter via {page_title} Smart Tag in all versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This is only exploitable on forms whose admin-authored confirmation message places the {page_title} Smart Tag inside an HTML attribute context.

Executive Summary

This vulnerability is a Reflected Cross-Site Scripting (XSS) issue in the WPForms plugin for WordPress. It occurs due to insufficient input sanitization and output escaping in the 'page_title' POST parameter. Attackers can inject malicious scripts into pages that execute when a user clicks a crafted link. Exploitation requires the admin-authored confirmation message to place the {page_title} Smart Tag inside an HTML attribute context.

Detection Guidance

Detection involves checking for vulnerable versions of the WPForms plugin. Inspect WordPress installations for versions up to and including 2.0.2. Look for forms using the {page_title} Smart Tag in confirmation messages within HTML attribute contexts.

Impact Analysis

An attacker could trick you into clicking a malicious link, leading to the execution of arbitrary web scripts in your browser. This may result in session hijacking, defacement of web pages, or theft of sensitive data like cookies or login credentials. The impact depends on user interaction and the context of the injected script.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, potentially violating GDPR (data protection) and HIPAA (health information privacy) requirements. If exploited, it may result in data breaches, triggering compliance obligations such as breach notifications and fines under these regulations.

Mitigation Strategies

Update the WPForms plugin to the latest version beyond 2.0.2. Remove or modify any forms using the {page_title} Smart Tag in confirmation messages placed inside HTML attributes. Implement input sanitization and output escaping for all form fields.
