CVE-2025-54722 is a reflected Cross-site Scripting (XSS) vulnerability identified in the Ex-Themes WooTour WordPress plugin, affecting versions up to and including 3.6.3. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code that is reflected back to users without proper sanitization. When a victim clicks on a crafted URL or interacts with a manipulated web page, the injected script executes in their browser context. This can lead to theft of sensitive information such as cookies, session tokens, or other credentials, enabling session hijacking or unauthorized actions on behalf of the user. The CVSS v3.1 base score is 7.1, indicating high severity, with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L. This means the attack can be launched remotely over the network without privileges but requires user interaction and has a high attack complexity. The vulnerability impacts confidentiality and integrity significantly, with a low impact on availability. No known public exploits or active exploitation campaigns have been reported yet. WooTour is a niche WordPress plugin used primarily by tourism-related websites to manage bookings and tours, making it a target for attackers seeking to compromise customer data or disrupt business operations. The vulnerability was reserved in July 2025 and published in November 2025, with no patch links currently available, indicating that remediation may still be pending or in progress.

For European organizations, especially those in the tourism and hospitality sectors using the WooTour plugin, this vulnerability poses a significant risk. Successful exploitation can lead to theft of user credentials, session hijacking, and unauthorized access to user accounts or administrative functions. This can result in data breaches involving personal customer information, financial loss, reputational damage, and potential regulatory penalties under GDPR due to compromised personal data. Additionally, attackers could deface websites or inject malicious content, undermining customer trust and business continuity. Since WooTour is used in booking and tour management, disruption or compromise could directly impact revenue streams. The requirement for user interaction means phishing or social engineering campaigns could be used to lure victims into triggering the exploit. Although no active exploits are known, the high CVSS score and the nature of the vulnerability warrant proactive defense measures. The impact is particularly critical for organizations with high volumes of customer interactions and sensitive data processed through WooTour-powered websites.

1. Monitor official Ex-Themes channels and Patchstack advisories for the release of a security patch addressing CVE-2025-54722 and apply it immediately upon availability. 2. In the interim, implement a Web Application Firewall (WAF) with robust XSS filtering rules to detect and block malicious input patterns targeting the WooTour plugin. 3. Employ strict input validation and output encoding on all user-supplied data within the WooTour plugin or custom code interacting with it, to prevent injection of executable scripts. 4. Educate users and administrators about the risks of clicking on suspicious links and implement anti-phishing measures to reduce the likelihood of successful social engineering. 5. Regularly audit and monitor web server logs and application behavior for signs of attempted XSS exploitation or anomalous activity related to WooTour endpoints. 6. Consider temporarily disabling or restricting access to vulnerable WooTour features if patching is delayed and risk is deemed unacceptable. 7. Ensure WordPress core, themes, and other plugins are kept up to date to reduce the overall attack surface and prevent chained exploits. 8. Implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context, mitigating the impact of potential XSS payloads.
