Publication date: 2026-07-10

Last updated on: 2026-07-14

Assigner: Wordfence

Description

The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' and 'check_out_date' parameters in all versions up to, and including, 2.3.1 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.

Attack-Flow Graph

Executive Summary

The WP Hotel Booking plugin for WordPress has a vulnerability known as Reflected Cross-Site Scripting (XSS) in its 'check_in_date' and 'check_out_date' parameters. This occurs because the plugin does not properly sanitize or escape input data in these parameters. As a result, an attacker who is not authenticated can inject malicious scripts into web pages. These scripts execute when a user is tricked into clicking a specially crafted link.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary scripts in the context of the affected website. This can lead to theft of user information, session hijacking, or performing actions on behalf of the user without their consent. Since the attack requires tricking a user into clicking a malicious link, it can compromise user trust and potentially lead to further exploitation of the website or its users.

Compliance Impact

The vulnerability in the WP Hotel Booking plugin allows reflected cross-site scripting (XSS) attacks, which can lead to unauthorized script execution in users' browsers. Such vulnerabilities can potentially expose personal data or session information if exploited, thereby increasing the risk of data breaches.

While the provided context does not explicitly mention compliance with standards like GDPR or HIPAA, vulnerabilities that enable unauthorized script execution and potential data exposure can negatively impact compliance with these regulations, which require protection of personal and sensitive data.

Mitigation Strategies

The vulnerability affects all versions of the WP Hotel Booking plugin up to and including 2.3.1. Immediate mitigation steps include updating the plugin to a version later than 2.3.1 where the issue is fixed.

Additionally, as this is a reflected cross-site scripting vulnerability via the 'check_in_date' and 'check_out_date' parameters, you should consider implementing web application firewall (WAF) rules to block suspicious input in these parameters until the plugin is updated.
