CVE-2025-7022 is a reflected Cross-Site Scripting (XSS) vulnerability identified in the My Reservation System WordPress plugin, specifically affecting all versions through 2.3. The vulnerability arises because the plugin fails to properly sanitize and escape user-supplied input parameters before reflecting them back in the web page output. This improper handling allows an attacker to inject malicious JavaScript code into the web page viewed by other users, particularly targeting high-privilege users such as administrators. When an admin or other privileged user clicks on a crafted URL containing the malicious payload, the injected script executes in their browser context. This can lead to session hijacking, credential theft, unauthorized actions performed with admin privileges, or redirection to malicious sites. The vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. Although no known exploits have been reported in the wild yet, the nature of reflected XSS makes it a significant risk, especially on administrative interfaces where elevated privileges can be abused. The lack of a patch or update at the time of publication further increases exposure. Since the plugin is used within WordPress environments, which are widely deployed for websites including booking and reservation systems, the attack surface is potentially broad. The vulnerability requires user interaction (clicking a malicious link) but no authentication bypass, as it targets authenticated users with high privileges. The absence of a CVSS score necessitates a severity assessment based on impact and exploitability factors.

For European organizations, this vulnerability poses a notable risk especially for businesses relying on the My Reservation System plugin to manage bookings, reservations, or customer interactions. Successful exploitation could lead to compromise of administrative accounts, enabling attackers to alter reservation data, access sensitive customer information, or disrupt service availability. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data exposure), financial losses, and operational disruptions. Organizations in sectors such as hospitality, travel, event management, and healthcare that use WordPress-based reservation systems are particularly vulnerable. The reflected XSS could also be leveraged as a stepping stone for broader network compromise if attackers gain administrative control. Given the plugin’s role in customer-facing services, exploitation could also erode customer trust and lead to legal liabilities. The threat is heightened in environments where administrators access the system from browsers without adequate security controls or where phishing defenses are weak.

To mitigate this vulnerability, organizations should: 1) Immediately audit their WordPress installations to identify if the My Reservation System plugin is in use and determine the version. 2) If possible, disable or remove the plugin until a security patch or update is released by the vendor. 3) Implement Web Application Firewall (WAF) rules to detect and block reflected XSS attack patterns targeting the plugin’s parameters. 4) Educate administrators and privileged users to avoid clicking on suspicious links, especially those received via email or messaging platforms. 5) Employ Content Security Policy (CSP) headers to restrict execution of unauthorized scripts in browsers. 6) Monitor logs for unusual access patterns or repeated attempts to exploit the reflected XSS. 7) Follow up with the plugin vendor for timely patches and apply updates as soon as they become available. 8) Consider isolating administrative interfaces behind VPNs or multi-factor authentication to reduce exposure. These steps go beyond generic advice by focusing on immediate containment, user awareness, and layered defenses tailored to the plugin’s context.
