CVE-2025-47680 is a high-severity vulnerability classified under CWE-79, which pertains to improper neutralization of input during web page generation, commonly known as Cross-site Scripting (XSS). This specific vulnerability affects the xili-tidy-tags plugin developed by Michel - xiligroup dev, up to version 1.12.06. The flaw allows an attacker to inject malicious scripts into web pages viewed by other users, resulting in reflected XSS attacks. Reflected XSS occurs when malicious input sent to a web application is immediately included in the response without proper sanitization or encoding, enabling execution of arbitrary JavaScript in the context of the victim's browser. The CVSS v3.1 base score of 7.1 indicates a high severity level, with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L highlighting that the attack can be launched remotely over the network without privileges, requires low attack complexity, no privileges, but does require user interaction (such as clicking a crafted link). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component, and the impact includes low confidentiality, integrity, and availability losses. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk, especially for websites using the xili-tidy-tags plugin for tag management in content management systems. Attackers could leverage this vulnerability to steal session cookies, perform actions on behalf of users, or redirect users to malicious sites, potentially leading to broader compromise or data leakage.

For European organizations, the impact of this vulnerability can be substantial, particularly for those relying on the xili-tidy-tags plugin within their web infrastructure. Exploitation could lead to unauthorized disclosure of sensitive user information, session hijacking, and manipulation of web content, undermining user trust and potentially violating data protection regulations such as the GDPR. The reflected XSS could be used as a vector for phishing campaigns targeting employees or customers, increasing the risk of credential theft or malware deployment. Additionally, the scope change in the vulnerability suggests that exploitation could affect multiple components or user sessions, amplifying the damage. Organizations in sectors with high web presence, such as e-commerce, finance, healthcare, and government services, are particularly vulnerable to reputational damage and regulatory penalties if user data is compromised. The requirement for user interaction means social engineering tactics could be employed, making awareness and user training critical. Given the interconnected nature of European digital services, a successful attack could also have cascading effects on supply chains and partner networks.

To mitigate this vulnerability effectively, European organizations should prioritize updating the xili-tidy-tags plugin to a version that addresses CVE-2025-47680 once available. In the absence of an official patch, organizations should implement strict input validation and output encoding on all user-supplied data that interacts with the plugin. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. Web Application Firewalls (WAFs) can be configured to detect and block common XSS attack patterns targeting the affected plugin. Conduct thorough code reviews and penetration testing focused on the plugin's integration points to identify and remediate injection vectors. Additionally, user awareness training should emphasize the risks of clicking on suspicious links, as user interaction is required for exploitation. Monitoring web logs for unusual request patterns and implementing multi-factor authentication can further reduce the risk of session hijacking and unauthorized access resulting from XSS attacks.
