CVE-2025-32926 is a critical security vulnerability classified as CWE-22, which refers to an improper limitation of a pathname to a restricted directory, commonly known as a Path Traversal vulnerability. This flaw exists in the ThemeGoods Grand Restaurant WordPress plugin, affecting all versions up to and including version 7.0. The vulnerability allows an unauthenticated attacker to manipulate file path inputs to access files and directories outside the intended restricted directory. Because the vulnerability does not require any privileges or user interaction (as indicated by the CVSS vector AV:N/AC:L/PR:N/UI:N), an attacker can remotely exploit this flaw over the network without authentication. Successful exploitation can lead to full compromise of confidentiality, integrity, and availability of the affected system, as attackers may read sensitive files, modify or delete critical data, or execute arbitrary code depending on the server configuration. The CVSS score of 9.8 reflects the critical nature of this vulnerability, highlighting its ease of exploitation and severe impact. No patches or fixes have been published at the time of this report, and no known exploits have been observed in the wild yet. However, the presence of this vulnerability in a widely used WordPress plugin that manages restaurant websites poses a significant risk to organizations relying on this software for their online presence and operations.

For European organizations, the impact of CVE-2025-32926 can be substantial. Many small and medium-sized enterprises (SMEs), including restaurants and hospitality businesses, use WordPress plugins like Grand Restaurant to manage their websites and online reservations. Exploitation of this vulnerability could lead to unauthorized disclosure of sensitive customer data, including personal information and payment details, violating GDPR regulations and resulting in heavy fines. Additionally, attackers could deface websites, disrupt online services, or use compromised servers as a foothold for further attacks within the corporate network. This could damage brand reputation and customer trust, especially in the hospitality sector which relies heavily on online bookings and customer engagement. The critical severity and ease of exploitation mean that attackers could rapidly compromise vulnerable sites, potentially leading to widespread incidents if not addressed promptly.

Given the absence of an official patch, European organizations should immediately audit their WordPress installations to identify the presence of the Grand Restaurant plugin and its version. Until a patch is available, organizations should consider disabling or uninstalling the plugin to eliminate the attack surface. Web application firewalls (WAFs) should be configured to detect and block suspicious path traversal attempts, such as those containing '../' sequences or other directory traversal patterns in URL parameters or POST data. Organizations should also implement strict input validation and sanitization at the web server or proxy level if possible. Regular backups of website data and configurations should be maintained to enable rapid recovery in case of compromise. Monitoring web server logs for unusual access patterns and scanning for indicators of compromise can help detect exploitation attempts early. Finally, organizations should subscribe to vendor and security advisories for timely updates and apply patches as soon as they become available.
