CVE-2025-47448: WP Hotel Booking CSRF Vulnerability

CVE-2025-47448 Overview

CVE-2025-47448 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the ThimPress WP Hotel Booking plugin for WordPress. The issue affects all versions of wp-hotel-booking up to and including 2.1.9. An attacker can craft a malicious web page or link that, when visited by an authenticated user, triggers unauthorized state-changing actions within the plugin. Exploitation requires user interaction but no privileges or authentication on the attacker's side.

Critical Impact
An attacker who tricks an authenticated WordPress user into visiting a malicious page can perform unauthorized actions against the WP Hotel Booking plugin on behalf of that user, resulting in limited integrity impact.

Affected Products

ThimPress WP Hotel Booking plugin for WordPress
All versions from n/a through 2.1.9
WordPress sites using the wp-hotel-booking plugin

Technical Details for CVE-2025-47448

Vulnerability Analysis

The vulnerability stems from missing or insufficient CSRF protections in the wp-hotel-booking plugin. WordPress provides a nonce mechanism (wp_nonce_field, check_admin_referer, and wp_verify_nonce) to prevent request forgery, but the affected plugin endpoints do not properly validate these tokens for one or more sensitive actions. As a result, requests originating from a third-party site can be treated as legitimate when accompanied by the victim's session cookies.

The vulnerability requires user interaction. An attacker must convince an authenticated user, typically an administrator or hotel manager, to click a link or visit a page containing crafted HTML or JavaScript. The impact is limited to integrity, with no direct confidentiality or availability consequences reported. See the Patchstack WP Hotel Booking CSRF Vulnerability advisory for additional context.

Root Cause

The root cause is the absence of proper anti-CSRF token validation on at least one state-changing request handler within the plugin. Without verifying a per-session nonce, the server cannot distinguish between an intentional user action and a forged request submitted by an attacker-controlled origin.

Attack Vector

The attack is delivered over the network and requires the victim to be authenticated to the target WordPress site. The attacker hosts a page containing a hidden form or fetch call targeting a vulnerable plugin endpoint. When the victim visits the page, the browser automatically attaches session cookies to the outbound request, and the server processes it as authorized. No exploitation code is verified for public release at this time.

Detection Methods for CVE-2025-47448

Indicators of Compromise

Unexpected changes to WP Hotel Booking configuration, bookings, or plugin data made by administrator accounts without corresponding admin panel activity.
HTTP POST or GET requests to wp-admin or admin-ajax.php endpoints related to wp-hotel-booking with Referer headers pointing to external, untrusted domains.
WordPress audit log entries showing administrative actions occurring immediately after the user visited a third-party site.

Detection Strategies

Enable and monitor a WordPress activity log plugin to record all administrative actions performed against the WP Hotel Booking plugin.
Inspect web server access logs for requests to plugin endpoints where the Referer header does not match the site's own domain.
Alert on state-changing plugin requests missing a valid _wpnonce parameter.

Monitoring Recommendations

Correlate WordPress admin session activity with recent browsing patterns of privileged users to identify suspicious follow-on actions.
Track the installed version of wp-hotel-booking across managed WordPress sites and alert when versions at or below 2.1.9 are detected.
Monitor for outbound links or emails sent to administrators containing suspicious URLs referencing wp-admin paths.

How to Mitigate CVE-2025-47448

Immediate Actions Required

Update the ThimPress WP Hotel Booking plugin to a version later than 2.1.9 as soon as a patched release is available from the vendor.
Restrict administrator and hotel manager accounts to dedicated browsers or sessions used only for WordPress administration.
Review recent plugin configuration and booking data for unauthorized modifications and revert as necessary.

Patch Information

Refer to the Patchstack WP Hotel Booking CSRF Vulnerability advisory for the latest patch status. Administrators should verify that the installed plugin version is higher than 2.1.9 and confirm the changelog explicitly references CSRF mitigations.

Workarounds

Deactivate the wp-hotel-booking plugin until a patched version is installed if the plugin is not actively required.
Deploy a Web Application Firewall (WAF) rule to block requests to WP Hotel Booking admin endpoints that lack a valid _wpnonce parameter or originate from an external Referer.
Require administrators to log out of WordPress before browsing untrusted sites and enforce short session lifetimes for privileged accounts.

bash

# Example WAF rule concept: block cross-origin POSTs to wp-hotel-booking endpoints
# ModSecurity-style pseudo-rule
SecRule REQUEST_URI "@contains wp-hotel-booking" \
  "chain,deny,status:403,id:1004744801,msg:'Blocked cross-origin request to WP Hotel Booking'"
  SecRule REQUEST_HEADERS:Referer "!@beginsWith https://your-site.example.com" "t:none"
