CVE-2025-22634 Overview
CVE-2025-22634 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Easy Booked – Appointment Booking and Scheduling Management System plugin for WordPress. The plugin, developed by MD Abu Jubayer Hossain, contains missing or insufficient anti-CSRF protections on state-changing requests. Attackers can trick authenticated users into submitting forged requests that modify plugin data without consent. The issue affects all versions of easy-booked up to and including 2.4.5. This weakness is classified under CWE-352: Cross-Site Request Forgery.
Critical Impact
An attacker can leverage a victim's authenticated WordPress session to perform unauthorized actions in the Easy Booked plugin, resulting in limited integrity and availability impact when the victim visits a malicious page.
Affected Products
- Easy Booked – Appointment Booking and Scheduling Management System for WordPress
- Plugin slug: easy-booked
- Versions from n/a through 2.4.5

Technical Details for CVE-2025-22634
Vulnerability Analysis
The Easy Booked plugin exposes actions that change server-side state without validating a per-request anti-CSRF token. WordPress provides the wp_nonce_field() and check_admin_referer() primitives to prevent this class of issue, but the affected handlers in easy-booked up to version 2.4.5 either omit nonce generation or fail to verify submitted nonces. As a result, requests originating from a third-party site are processed with the full privileges of the currently authenticated victim. Exploitation requires user interaction, typically clicking a crafted link or loading an attacker-controlled page while logged into WordPress. The impact is scoped to actions the victim can perform in the plugin, including modifying booking configuration or related records.
Root Cause
The root cause is missing CSRF protection on privileged plugin endpoints. Request handlers do not enforce nonce validation before executing state-changing operations, and they rely solely on ambient session authentication.
Attack Vector
The attack vector is network-based and requires user interaction. An attacker hosts an HTML page or injects markup containing a form or image tag that auto-submits to a vulnerable Easy Booked endpoint. When an authenticated WordPress user with access to the plugin visits the page, the browser attaches session cookies and the request executes server-side. No credentials or elevated privileges are required from the attacker. See the Patchstack advisory for additional technical details.
Detection Methods for CVE-2025-22634
Indicators of Compromise
- Unexpected changes to Easy Booked plugin settings, appointment records, or scheduling configuration that do not correlate with legitimate administrator activity.
- POST requests to easy-booked plugin endpoints where the HTTP Referer header points to an external domain.
- WordPress access log entries showing state-changing requests without an accompanying nonce parameter such as _wpnonce.
Detection Strategies
- Review WordPress audit logs for plugin configuration changes and correlate timestamps with user browsing activity.
- Deploy a Web Application Firewall (WAF) rule that flags POST requests to wp-admin/admin.php?page=easy-booked* lacking a valid _wpnonce value.
- Monitor for cross-origin Referer headers on authenticated administrative requests to the WordPress backend.
Monitoring Recommendations
- Enable a WordPress audit logging plugin to capture user, IP, and request context for every plugin configuration change.
- Forward WordPress and reverse-proxy logs to a centralized SIEM to correlate suspicious referrer patterns with administrator sessions.
- Alert on newly created or modified booking records outside of expected business hours.
How to Mitigate CVE-2025-22634
Immediate Actions Required
- Update the Easy Booked plugin to a version later than 2.4.5 as soon as the vendor releases a patched release.
- If no fixed version is available, deactivate and remove the easy-booked plugin from production WordPress sites.
- Require administrators to log out of WordPress when finished and avoid browsing untrusted sites in the same browser session.
Patch Information
At the time of the last NVD update on 2026-06-17, the advisory tracked by Patchstack lists all versions through 2.4.5 as affected. Administrators should monitor the plugin's WordPress.org page and the Patchstack database for a fixed release and apply it promptly.
Workarounds
- Restrict access to the WordPress admin interface by IP allowlist at the web server or WAF layer.
- Deploy a WAF rule that blocks POST requests to Easy Booked administrative endpoints when the Referer header is missing or off-domain.
- Enforce SameSite=Strict or SameSite=Lax attributes on WordPress authentication cookies to reduce cross-site request success.
