CVE-2025-67922 is a reflected cross-site scripting (XSS) vulnerability identified in the ThemeGoods Grand Restaurant plugin, affecting all versions prior to 7.0.9. The vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing malicious scripts to be injected and executed in the context of a victim's browser. This type of XSS is 'reflected,' meaning the malicious payload is embedded in a URL or request and reflected back in the server's response without proper sanitization or encoding. An attacker can exploit this by crafting a malicious link that, when visited by a user, executes arbitrary JavaScript code. Potential consequences include session hijacking, credential theft, defacement, or redirection to malicious sites. The vulnerability does not require authentication, increasing its risk profile, and does not depend on user interaction beyond clicking a malicious link. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and patched in version 7.0.9. The lack of a CVSS score necessitates an assessment based on impact and exploitability factors. The plugin is commonly used in WordPress sites focused on restaurant and hospitality services, which often handle customer data and online reservations, making them attractive targets for attackers. The vulnerability's root cause is insufficient input validation and output encoding in the plugin's web page generation logic.

For European organizations, especially those operating in the hospitality and restaurant sectors using the ThemeGoods Grand Restaurant plugin, this vulnerability can lead to significant risks. Exploitation can compromise the confidentiality of user data, including personal and payment information, through session hijacking or credential theft. Integrity of website content can be undermined by script injection, potentially damaging brand reputation and customer trust. Availability is less directly impacted but could be affected if attackers use XSS to inject disruptive scripts or redirect users to malicious sites. The vulnerability's ease of exploitation without authentication increases the attack surface, particularly for public-facing websites. Given the widespread use of WordPress and its plugins in Europe, the threat could affect numerous small to medium enterprises that may lack robust security controls. Regulatory implications under GDPR also arise if personal data is compromised, potentially leading to fines and legal consequences.

The primary mitigation is to update the ThemeGoods Grand Restaurant plugin to version 7.0.9 or later, where the vulnerability is patched. Organizations should verify plugin versions across all WordPress instances and apply updates promptly. In addition, implement strict input validation and output encoding on all user-supplied data to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Regularly audit and monitor web application logs for suspicious requests that may indicate attempted exploitation. Educate users and administrators about the risks of clicking unknown or suspicious links. Consider deploying web application firewalls (WAFs) configured to detect and block reflected XSS payloads targeting this plugin. Finally, maintain a robust patch management process to quickly address future vulnerabilities.
