CVE-2025-62063 is a cross-site scripting (XSS) vulnerability affecting the WP Travel Gutenberg Blocks plugin for WordPress, specifically versions up to and including 3.9.2. The vulnerability stems from improper neutralization of input during the generation of web pages, which allows malicious actors to inject and execute arbitrary scripts in the context of the affected website. This can lead to session hijacking, defacement, or unauthorized actions performed on behalf of authenticated users. The vulnerability requires the attacker to have low privileges within the WordPress environment and necessitates user interaction, such as clicking a crafted link or viewing a malicious page. The CVSS 3.1 base score is 6.5, reflecting medium severity, with attack vector being network (remote), low attack complexity, requiring privileges, user interaction, and impacting confidentiality, integrity, and availability with limited scope. No known exploits have been reported in the wild as of the publication date. The vulnerability affects a widely used plugin in the travel sector, which integrates with the Gutenberg editor to provide travel-related blocks, making it a target for attackers aiming to compromise travel websites or steal user data. The issue was reserved on October 7, 2025, and published on October 22, 2025, by Patchstack. No official patches or mitigation links were provided at the time of reporting, indicating the need for vigilance and proactive defense measures.

For European organizations, especially those operating travel-related websites using WordPress with the WP Travel Gutenberg Blocks plugin, this vulnerability poses a risk of unauthorized script execution leading to data theft, session hijacking, and potential defacement or disruption of services. Confidentiality of user data can be compromised, including personal and payment information commonly handled by travel sites. Integrity of website content and transactions may be undermined, damaging brand reputation and customer trust. Availability could be affected if attackers leverage the vulnerability to perform denial-of-service or disruptive actions. Given the travel sector's importance in Europe, such attacks could have significant economic and operational consequences. The requirement for low privileges and user interaction lowers the barrier for exploitation, increasing the risk if users are tricked into interacting with malicious content. Organizations with high traffic and customer engagement are particularly vulnerable to reputational damage and regulatory scrutiny under GDPR if personal data is exposed.

1. Monitor WP Travel’s official channels for security patches and apply updates to the WP Travel Gutenberg Blocks plugin immediately upon release. 2. Employ strict input validation and output encoding within the WordPress environment to prevent injection of malicious scripts. 3. Use Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on web pages. 4. Deploy a Web Application Firewall (WAF) configured to detect and block common XSS attack patterns targeting WordPress plugins. 5. Educate site administrators and users about the risks of interacting with suspicious links or content to reduce the likelihood of successful user interaction exploitation. 6. Regularly audit and review installed plugins for security compliance and remove or replace outdated or unsupported plugins. 7. Implement multi-factor authentication (MFA) for WordPress admin accounts to reduce the impact of compromised credentials. 8. Conduct periodic security assessments and penetration testing focusing on plugin vulnerabilities and input handling.
