CVE-2025-22725 identifies a Stored Cross-Site Scripting (XSS) vulnerability in the loopus WP Virtual Assistant WordPress plugin, versions up to 3.0. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows malicious scripts to be stored and later executed in the browsers of users who view the affected pages. This type of vulnerability can be exploited by an attacker with at least low privileges (PR:L) on the WordPress site, who can inject malicious payloads that require user interaction (UI:R) to trigger. The vulnerability has a CVSS 3.1 base score of 5.4, indicating medium severity, with attack vector being network (AV:N), low attack complexity (AC:L), and scope change (S:C), meaning the impact extends beyond the vulnerable component. The confidentiality and integrity impacts are limited (C:L, I:L), with no availability impact (A:N). Stored XSS can lead to session hijacking, theft of cookies, defacement, or unauthorized actions performed on behalf of users, especially administrators or editors. No public exploits are currently known, but the vulnerability is published and should be addressed promptly. The plugin is used in WordPress environments, which are widely deployed across various sectors, including business, government, and e-commerce. The lack of available patches at the time of reporting increases the urgency for interim mitigations.

For European organizations, the impact of this vulnerability can be significant, particularly for those relying on the loopus WP Virtual Assistant plugin within their WordPress infrastructure. Successful exploitation could allow attackers to execute arbitrary JavaScript in the context of the affected site, potentially leading to session hijacking, credential theft, or unauthorized actions performed with the privileges of the victim user. This can compromise the confidentiality and integrity of sensitive data and disrupt trust in web services. Organizations in sectors such as finance, healthcare, and government, where WordPress is used for public-facing or internal portals, may face reputational damage and regulatory consequences under GDPR if personal data is exposed. The requirement for some privileges and user interaction reduces the likelihood of mass exploitation but does not eliminate targeted attacks against privileged users. The absence of known exploits currently provides a window for mitigation before active exploitation occurs.

1. Monitor vendor communications closely and apply official patches or updates for the loopus WP Virtual Assistant plugin as soon as they become available. 2. Until patches are released, restrict access to the plugin’s input interfaces to trusted users only, minimizing the risk of malicious input injection. 3. Implement strict input validation and sanitization on all user-supplied data fields related to the plugin to prevent injection of malicious scripts. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers, mitigating the impact of stored XSS. 5. Conduct regular security audits and penetration testing focusing on WordPress plugins and their input handling. 6. Educate privileged users about the risks of interacting with untrusted content and encourage cautious behavior to reduce user interaction risks. 7. Consider disabling or replacing the plugin if it is not essential or if no timely patch is forthcoming. 8. Maintain up-to-date backups and incident response plans to quickly recover from potential compromises.
