CVE-2025-62069 identifies a cross-site scripting (XSS) vulnerability in the RealMag777 MDTF (Meta Data and Taxonomy Filter) WordPress plugin, specifically versions up to 1.3.3.8. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows an attacker to inject malicious scripts into web pages viewed by other users. The CVSS 3.1 score of 6.5 indicates a medium severity, with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. This means the attack can be launched remotely over the network with low attack complexity, requires low privileges (authenticated user), and user interaction (victim must click or visit a crafted page). The scope is changed, indicating the vulnerability affects components beyond the initially vulnerable one. The impact includes limited confidentiality loss (e.g., session tokens), integrity compromise (e.g., content manipulation), and availability degradation (e.g., script-based denial of service). No known public exploits exist yet, but the vulnerability is published and should be addressed proactively. The plugin is commonly used in WordPress environments to filter metadata and taxonomies, making it a target in websites relying on this functionality. The lack of patch links suggests a patch may not yet be released, emphasizing the need for interim mitigations.

For European organizations, this vulnerability poses a risk primarily to websites using the RealMag777 MDTF plugin, which is popular among WordPress sites that require advanced filtering of metadata and taxonomies. Exploitation could lead to session hijacking, unauthorized actions on behalf of users, defacement, or malware distribution, impacting customer trust and regulatory compliance, especially under GDPR. Public sector websites, e-commerce platforms, and media outlets are particularly vulnerable due to their reliance on WordPress and the potential high visibility of attacks. The requirement for authenticated low-privilege access means insider threats or compromised user accounts could be leveraged. The vulnerability’s ability to affect confidentiality, integrity, and availability can disrupt business operations and lead to data breaches, with potential legal and financial consequences under European data protection laws.

1. Monitor RealMag777 vendor channels and Patchstack for official patches and apply them immediately upon release. 2. In the absence of a patch, implement Web Application Firewall (WAF) rules to detect and block typical XSS payloads targeting the MDTF plugin’s input fields. 3. Restrict user privileges to the minimum necessary, especially limiting who can input or manipulate metadata and taxonomy filters. 4. Conduct regular security audits and code reviews of customizations involving the MDTF plugin to identify and sanitize inputs properly. 5. Educate users about phishing and social engineering risks to reduce the likelihood of user interaction with malicious links. 6. Utilize Content Security Policy (CSP) headers to reduce the impact of potential XSS by restricting script execution sources. 7. Monitor logs for unusual activities related to the plugin’s input fields to detect exploitation attempts early.
