WP Hotel Booking check-in dates allow reflected script injection

WP Hotel Booking 2.3.2 and earlier places the check_in_date request value back into rendered output without adequate sanitization and escaping. A remote attacker can prepare a link whose date value contains script; the code runs only when a victim opens the link, but it runs in the affected site's origin and can act with that visitor's browser permissions.

Component: WP Hotel Booking
Plugin slug: wp-hotel-booking
Affected: <= 2.3.2
Safe version: See mitigation notes
Published: Jul 17, 2026
Weakness: CWE-79 — Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

This CVE was published Jul 17, 2026 and is one of 26 known issues for this plugin.

What to do

Update, patch or deactivate.

Update WP Hotel Booking to a release newer than 2.3.2. The official upstream changelog lists version 2.3.4, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' parameter in all versions up to, and including, 2.3.2 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.
