CVE-2025-63026 identifies a stored cross-site scripting (XSS) vulnerability in the ThemeGoods Grand Restaurant Theme Elements plugin for Elementor, a popular WordPress page builder. The vulnerability is due to improper neutralization of user-supplied input during the generation of web pages, allowing attackers to inject malicious scripts that are stored persistently within the website's content. When other users or administrators view the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed with the victim's privileges. The vulnerability affects all versions up to and including 2.1.1. The CVSS v3.1 base score is 5.4, indicating medium severity, with the vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. This means the attack can be launched remotely over the network with low attack complexity, requires privileges (likely contributor or editor roles) and user interaction (victim must view the malicious content). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. Confidentiality and integrity impacts are low, while availability is not affected. No patches or known exploits are currently reported, but the vulnerability's nature suggests it could be exploited in targeted attacks. The plugin is commonly used in restaurant and hospitality websites built on WordPress, which are often targeted for defacement or phishing campaigns.

For European organizations, particularly those in the hospitality sector using WordPress with the Grand Restaurant Theme Elements plugin, this vulnerability poses a risk of persistent cross-site scripting attacks. Attackers could exploit this to steal session cookies, impersonate users, inject malicious content, or redirect visitors to phishing sites. This can lead to reputational damage, loss of customer trust, and potential regulatory consequences under GDPR if personal data is compromised. The medium severity score reflects that while the vulnerability requires some privileges and user interaction, the impact on confidentiality and integrity can facilitate further attacks or unauthorized access. Given the widespread use of WordPress in Europe and the importance of the hospitality industry, exploitation could disrupt business operations and customer engagement. Additionally, compromised sites could be used as platforms for broader attacks, including malware distribution or supply chain attacks.

Organizations should immediately inventory their WordPress installations to identify if the Grand Restaurant Theme Elements plugin is in use and confirm the version. Since no patch links are currently provided, monitor vendor announcements for updates and apply patches promptly once available. In the interim, restrict user roles to minimize privileges that allow content editing or theme element modification. Implement strict input validation and output encoding on all user-supplied data to prevent script injection. Deploy a web application firewall (WAF) with rules to detect and block XSS payloads, especially those targeting known plugin parameters. Conduct regular security audits and penetration testing focused on plugin vulnerabilities. Educate content editors and administrators about the risks of XSS and safe content management practices. Consider disabling or replacing the vulnerable plugin if immediate patching is not feasible. Maintain robust backup and incident response plans to recover quickly from any compromise.
