CVE-2025-48077 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Block Country plugin by nitinmaurya12, which is used to restrict access based on geographic locations. The vulnerability affects all versions up to and including 1.0. CSRF vulnerabilities allow attackers to trick authenticated users into submitting unauthorized requests to a web application, exploiting the trust a site has in the user's browser. In this case, the CSRF flaw enables Stored Cross-Site Scripting (XSS), where malicious scripts injected by an attacker are permanently stored on the target server and executed in the context of other users' browsers. The CVSS 3.1 score of 8.8 reflects a high-severity issue with network attack vector, low attack complexity, no privileges required, but requiring user interaction. The impact covers confidentiality, integrity, and availability, meaning attackers can steal sensitive data, manipulate site content, or disrupt services. Although no known exploits are reported in the wild, the lack of available patches increases risk. The vulnerability likely stems from insufficient CSRF token validation and inadequate input sanitization in the plugin's request handling. This makes it possible for attackers to craft malicious links or forms that, when visited or submitted by an authenticated user, execute arbitrary scripts stored on the server, compromising user sessions and data.

For European organizations, this vulnerability poses significant risks, especially for those relying on the Block Country plugin to manage access controls or geo-restrictions on their websites. Exploitation can lead to unauthorized actions performed with the privileges of legitimate users, including administrators, resulting in data breaches, defacement, or service disruption. Stored XSS can facilitate session hijacking, credential theft, or distribution of malware to site visitors, impacting customer trust and regulatory compliance under GDPR. The broad impact on confidentiality, integrity, and availability could lead to financial losses, reputational damage, and legal consequences. Organizations with public-facing web applications, e-commerce platforms, or portals handling personal data are particularly vulnerable. The absence of patches and known exploits in the wild suggests a window of opportunity for attackers to develop exploits, emphasizing the need for proactive defenses.

European organizations should immediately audit their use of the Block Country plugin and consider disabling it until a secure update is released. Implement strict CSRF protections by enforcing anti-CSRF tokens on all state-changing requests and validating their presence server-side. Enhance input validation and output encoding to prevent Stored XSS, especially on user-controllable fields. Employ Content Security Policy (CSP) headers to restrict script execution and reduce XSS impact. Monitor web server logs and application behavior for unusual or unauthorized requests indicative of CSRF or XSS attempts. Educate users about the risks of clicking unsolicited links or submitting forms from untrusted sources to reduce the likelihood of successful CSRF exploitation. Regularly update all web application components and subscribe to vulnerability advisories for timely patching. Consider deploying Web Application Firewalls (WAFs) with rules targeting CSRF and XSS attack patterns to provide an additional layer of defense.
