CVE-2025-22669: Awesome Event Booking CSRF Vulnerability

CVE-2025-22669 Overview

CVE-2025-22669 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting the AwesomeTOGI Awesome Event Booking plugin for WordPress. The flaw impacts all versions up to and including 2.7.5. An attacker can trick an authenticated user into submitting a forged HTTP request that performs unintended actions on the vulnerable site. Exploitation requires user interaction, typically by luring a victim to a malicious page or link. The Patchstack WordPress Vulnerability Report tracks the issue.

Critical Impact
Attackers can perform state-changing plugin actions in the context of an authenticated victim, resulting in limited integrity impact on affected WordPress sites.

Affected Products

Technical Details for CVE-2025-22669

Vulnerability Analysis

The Awesome Event Booking plugin fails to validate the origin and authenticity of state-changing HTTP requests. Specifically, sensitive plugin actions do not verify a WordPress nonce token before executing. An attacker who convinces an authenticated user to visit an attacker-controlled page can trigger those actions using the victim's session cookies.

The attacker cannot read responses because the browser same-origin policy blocks cross-origin reads. However, the request itself executes with the victim's privileges. This provides an integrity impact without directly exposing confidential data or crashing the service.

Root Cause

The root cause is missing CSRF protection [CWE-352] on plugin request handlers. WordPress provides the wp_nonce_field() and check_admin_referer() primitives to validate that requests originate from a legitimate session. The vulnerable handlers in awesome-event-booking up to version 2.7.5 do not invoke these checks before processing form submissions.

Attack Vector

Exploitation follows the standard CSRF pattern. The attacker crafts an HTML page containing a hidden form or image tag that submits a request to the target WordPress site. When an authenticated administrator or privileged user loads that page, the browser attaches the WordPress authentication cookie automatically. The forged request reaches the vulnerable endpoint and executes as the victim.

The attack requires user interaction, and privileges required are none for the attacker. See the Patchstack advisory for additional technical details.

Detection Methods for CVE-2025-22669

Indicators of Compromise

Unexpected changes to Awesome Event Booking configuration, events, or bookings performed by administrator accounts
HTTP referer headers from unrelated third-party domains in WordPress access logs targeting plugin endpoints
POST requests to awesome-event-booking handlers lacking a valid _wpnonce parameter

Detection Strategies

Audit WordPress access logs for POST requests to plugin endpoints with external Referer values or missing Origin headers
Correlate administrative changes in the plugin with user browsing activity to identify suspicious cross-site triggers
Enumerate installed WordPress plugins and flag any awesome-event-booking install at version 2.7.5 or earlier

Monitoring Recommendations

Enable WordPress audit logging plugins to capture administrator actions with timestamps and source IPs
Alert on plugin configuration changes occurring outside normal administrative hours
Monitor egress web traffic from administrator workstations for connections to unknown domains prior to WordPress changes

How to Mitigate CVE-2025-22669

Immediate Actions Required

Identify all WordPress instances running the awesome-event-booking plugin at version 2.7.5 or earlier
Update the plugin to a version above 2.7.5 once a vendor-patched release is available
Restrict administrator sessions by requiring re-authentication and short cookie lifetimes
Instruct administrators to log out of WordPress before browsing untrusted sites

Patch Information

Refer to the Patchstack WordPress Vulnerability Report for current patch status. The vulnerability affects all versions up to and including 2.7.5. Apply the vendor-supplied update as soon as it is released and verify the plugin version after upgrade.

Workarounds

Deactivate the Awesome Event Booking plugin until an upstream patch is applied
Deploy a Web Application Firewall (WAF) rule that blocks POST requests to plugin endpoints missing a valid _wpnonce parameter
Enforce SameSite=Strict or SameSite=Lax on WordPress session cookies to reduce cross-site cookie transmission
Require multi-factor authentication for administrator accounts to limit downstream impact

bash

# Configuration example: nginx rule to block plugin requests missing nonce
location ~* /wp-admin/admin-ajax\.php {
    if ($request_method = POST) {
        if ($arg_action ~* "awesome_event_booking") {
            if ($arg__wpnonce = "") { return 403; }
        }
    }
}
