CVE-2025-62074 is a cross-site scripting (XSS) vulnerability identified in the Amauri WPMobile.App WordPress plugin, affecting all versions up to and including 11.71. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious JavaScript code into pages rendered by the plugin. This type of vulnerability is typically exploited by tricking a user into visiting a specially crafted URL or interacting with malicious content, which then executes the injected script in the context of the victim's browser. The CVSS 3.1 base score of 7.1 reflects that the attack vector is network-based (remote), requires no privileges, but does require user interaction, and the impact affects confidentiality, integrity, and availability to a limited extent. The scope is changed, indicating that the vulnerability can affect components beyond the vulnerable plugin itself, potentially impacting the entire WordPress site. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the widespread use of WordPress and the popularity of the WPMobile.App plugin for mobile site optimization. The lack of an official patch at the time of publication means that organizations must rely on interim mitigations. The vulnerability could be leveraged to steal session cookies, perform phishing attacks, or deface websites, undermining user trust and potentially leading to broader compromise if administrative credentials are exposed.

For European organizations, the impact of CVE-2025-62074 can be substantial, especially for those relying on WordPress sites enhanced by the WPMobile.App plugin. Successful exploitation can lead to unauthorized disclosure of sensitive user data, session hijacking, and manipulation of website content, which can damage brand reputation and customer trust. E-commerce platforms, media outlets, and public sector websites are particularly vulnerable due to their high visibility and reliance on user interaction. The integrity and availability of websites may be compromised, resulting in downtime or defacement that disrupts business operations. Additionally, attackers could use the vulnerability as a foothold for further attacks within the network, especially if administrative credentials are compromised. Given the interconnected nature of European digital infrastructure and stringent data protection regulations such as GDPR, exploitation could also lead to regulatory penalties and legal consequences. The absence of known exploits currently provides a window for proactive defense, but the high severity score underscores the urgency for mitigation.

European organizations should implement a multi-layered defense strategy to mitigate CVE-2025-62074. First, monitor official channels for the release of a security patch from Amauri and apply it immediately upon availability. Until a patch is available, deploy web application firewalls (WAFs) with rules specifically designed to detect and block XSS payloads targeting the WPMobile.App plugin. Implement strict Content Security Policies (CSP) to restrict the execution of unauthorized scripts in browsers. Conduct regular security audits and code reviews of WordPress plugins and themes to identify and remediate similar vulnerabilities proactively. Educate users and administrators about the risks of clicking on suspicious links or interacting with untrusted content. Limit the exposure of administrative interfaces by enforcing strong authentication mechanisms and IP whitelisting where feasible. Maintain up-to-date backups of website data to enable rapid recovery in case of defacement or compromise. Finally, integrate security monitoring tools to detect anomalous behavior indicative of exploitation attempts.
