CVE-2025-62885 is a DOM-based Cross-site Scripting (XSS) vulnerability found in the RexTheme WP VR WordPress plugin, affecting versions up to and including 8.5.42. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows malicious scripts to be injected and executed within the victim's browser context. This type of XSS is client-side and occurs when the web application uses unsafe JavaScript methods to process URL fragments or other client-side inputs without proper sanitization. Exploitation requires an attacker to have low privileges (PR:L) on the WordPress site and involves user interaction (UI:R), such as tricking a user into clicking a crafted link. The vulnerability has a CVSS 3.1 base score of 6.5, indicating medium severity, with impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. No known public exploits have been reported yet. The vulnerability was reserved on October 24, 2025, and published on October 27, 2025. The plugin WP VR is used to create virtual reality tours on WordPress sites, and its user base includes various organizations that rely on immersive web content. The lack of a patch link suggests that a fix is either pending or not yet publicly available. Given the nature of DOM-based XSS, attackers can steal session cookies, perform actions on behalf of users, or redirect users to malicious sites, potentially leading to broader compromise.

For European organizations, the impact of CVE-2025-62885 can be significant, especially for those relying on the WP VR plugin to deliver virtual reality content on their WordPress sites. Successful exploitation could lead to session hijacking, unauthorized actions performed with user privileges, theft of sensitive information, and defacement or manipulation of website content. This can damage organizational reputation, lead to data breaches involving personal or business-critical data, and disrupt service availability. Given the medium severity and requirement for user interaction, the risk is moderate but non-negligible. Organizations in sectors such as tourism, real estate, education, and cultural heritage—where virtual tours are common—may face higher exposure. Additionally, the cross-site scripting vulnerability can be leveraged as a stepping stone for more advanced attacks, including phishing campaigns or malware distribution. The scope change indicates that the vulnerability could impact other components or users beyond the initially vulnerable plugin, increasing the potential blast radius within affected websites.

To mitigate CVE-2025-62885, European organizations should take immediate and specific actions beyond generic advice: 1) Monitor RexTheme and WP VR plugin vendor channels closely for official patches and apply updates promptly once available. 2) Until a patch is released, implement strict Content Security Policies (CSP) to restrict the execution of inline scripts and limit sources of executable code, reducing the risk of malicious script execution. 3) Review and sanitize all user inputs and URL parameters processed by the WP VR plugin, particularly those used in client-side scripts, to prevent injection of malicious payloads. 4) Limit the privileges of users who can upload or modify content within WordPress to reduce the risk of attackers gaining the necessary low privileges to exploit the vulnerability. 5) Educate users and administrators about the risks of clicking untrusted links, especially those that may contain crafted URL fragments targeting the DOM-based XSS. 6) Employ web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting WordPress plugins. 7) Conduct regular security audits and penetration testing focused on client-side vulnerabilities in WordPress environments hosting WP VR. 8) Consider temporarily disabling or restricting access to the WP VR plugin if immediate patching is not feasible and the risk is deemed high.
