CVE-2025-47519: Easy PayPal Events Plugin CSRF Vulnerability

CVE-2025-47519 Overview

CVE-2025-47519 is a Cross-Site Request Forgery (CSRF) vulnerability in the Scott Paterson Easy PayPal Events WordPress plugin (easy-paypal-events-tickets). The flaw affects all versions up to and including 1.2.2. Attackers can trick authenticated users into submitting forged requests that perform unintended state-changing actions in the plugin. The issue is classified under CWE-352 and requires user interaction over the network. Successful exploitation results in limited integrity impact without compromising confidentiality or availability.

Critical Impact
Attackers can coerce authenticated WordPress users into executing unintended plugin actions by luring them to a malicious page, leading to unauthorized state changes within Easy PayPal Events.

Affected Products

Scott Paterson Easy PayPal Events (easy-paypal-events-tickets) — versions up to and including 1.2.2
WordPress installations with the vulnerable plugin activated
Sites where administrators or privileged users interact with attacker-controlled links

Technical Details for CVE-2025-47519

Vulnerability Analysis

The Easy PayPal Events plugin fails to validate the origin and authenticity of state-changing HTTP requests. The plugin does not enforce a valid WordPress nonce (wp_nonce) or an equivalent anti-CSRF token on privileged actions. As a result, a browser session belonging to an authenticated WordPress user can be abused to submit requests forged by an external site. Because the vulnerability requires user interaction, an attacker must convince the victim to visit or interact with a crafted page while logged into WordPress.

Root Cause

The root cause is missing CSRF protection on plugin endpoints that modify server-side state. WordPress provides the wp_nonce_field() and check_admin_referer() primitives for exactly this purpose. The affected plugin versions omit these checks, so the server accepts any request that carries valid session cookies regardless of origin.

Attack Vector

Exploitation proceeds over the network and requires the victim to click a link or load attacker-controlled content. The attacker hosts a page containing an auto-submitting form or image tag that targets a vulnerable Easy PayPal Events endpoint. When the authenticated victim loads the page, the browser attaches session cookies to the outbound request. The plugin processes the request as if it were legitimate, modifying data within the scope of the victim's privileges.

No verified proof-of-concept code is publicly available. Refer to the Patchstack advisory for technical details.

Detection Methods for CVE-2025-47519

Indicators of Compromise

Unexpected modifications to event, ticket, or PayPal configuration data within the Easy PayPal Events plugin.
HTTP POST or GET requests to plugin endpoints with Referer headers pointing to external, untrusted domains.
Administrative actions logged from user sessions immediately after those users visited unfamiliar external URLs.

Detection Strategies

Review web server access logs for requests to easy-paypal-events-tickets endpoints that lack a matching same-origin Referer header.
Correlate WordPress audit logs with browser history or email gateway logs to identify links that preceded suspicious plugin actions.
Deploy a Web Application Firewall (WAF) rule that flags plugin state-changing requests missing nonce parameters.

Monitoring Recommendations

Enable a WordPress activity logging plugin to capture administrative changes with user, IP, and timestamp context.
Monitor outbound email and messaging channels for phishing lures that reference WordPress administration URLs.
Alert on new or modified events, tickets, and PayPal payee addresses within the plugin database tables.

How to Mitigate CVE-2025-47519

Immediate Actions Required

Deactivate the Easy PayPal Events plugin until a patched release beyond version 1.2.2 is available.
Force administrators and privileged users to log out and re-authenticate to invalidate active sessions.
Instruct privileged users to avoid clicking untrusted links while authenticated to WordPress.

Patch Information

No fixed version has been published at the time of NVD disclosure. Consult the Patchstack WordPress Vulnerability Report for the latest vendor status and any subsequent patched releases.

Workarounds

Restrict access to the WordPress admin interface by IP allow-listing at the web server or WAF layer.
Deploy a WAF rule that blocks requests to the plugin missing a valid _wpnonce parameter or with cross-origin Referer headers.
Enforce the SameSite=Lax or SameSite=Strict attribute on WordPress session cookies to reduce cross-site request risk.

bash

# Example nginx rule to block cross-origin POSTs to the plugin
location ~* /wp-content/plugins/easy-paypal-events-tickets/ {
    if ($request_method = POST) {
        set $block "1";
    }
    if ($http_referer ~* "^https?://yourdomain\.com/") {
        set $block "0";
    }
    if ($block = "1") {
        return 403;
    }
}
