CVE-2025-47519 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Scott Paterson Easy PayPal Events plugin, affecting versions up to 1.2.2. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a web application where the user is currently authenticated, without their consent or knowledge. In this case, the Easy PayPal Events plugin does not adequately verify the origin or intent of requests that modify event-related data or payment settings, allowing attackers to craft malicious web pages or links that, when visited by an authenticated administrator or user, could cause unauthorized actions to be performed on their behalf. The CVSS 3.1 base score of 4.3 (medium severity) reflects that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and impacts integrity (I:L) without affecting confidentiality or availability. There are no known exploits in the wild, and no patches have been published yet. The vulnerability is classified under CWE-352, indicating a failure to implement anti-CSRF tokens or other effective CSRF protections. This vulnerability is particularly relevant for websites using the Easy PayPal Events plugin to manage event payments via PayPal, as it could allow attackers to manipulate event payment settings or registrations without authorization.

For European organizations using the Easy PayPal Events plugin, this vulnerability could lead to unauthorized modifications of event payment configurations or registrations, potentially resulting in financial discrepancies, fraudulent event registrations, or disruption of event management workflows. While the vulnerability does not directly expose sensitive data or cause service outages, the integrity impact could undermine trust in event payment processing and lead to financial losses or reputational damage. Organizations involved in event management, ticketing, or fundraising relying on this plugin are at risk. Given the requirement for user interaction and no privileges needed, phishing or social engineering campaigns could be used to exploit this vulnerability, increasing the risk. The impact is more pronounced for organizations with high volumes of event transactions or those handling sensitive financial data through the plugin.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Immediately review and restrict administrative access to the Easy PayPal Events plugin to trusted users only, minimizing the attack surface. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF-like requests targeting the plugin endpoints. 3) Educate users and administrators about the risks of clicking on untrusted links or visiting suspicious websites while logged into administrative accounts. 4) Monitor logs for unusual or unauthorized changes in event payment settings or registrations. 5) If possible, disable or limit the use of the Easy PayPal Events plugin until a vendor patch is released. 6) Implement additional CSRF protections at the application or server level, such as verifying HTTP Referer headers or using anti-CSRF tokens via custom development or third-party security plugins. 7) Stay alert for vendor updates or patches and apply them promptly once available.
