CVE-2025-47611 is a high-severity reflected Cross-site Scripting (XSS) vulnerability affecting the 'User Meta' product developed by Khaled, up to version 3.1.2. The vulnerability is classified under CWE-79, which involves improper neutralization of input during web page generation. Specifically, the flaw allows malicious actors to inject and execute arbitrary scripts in the context of a victim's browser when they interact with crafted URLs or inputs that are not properly sanitized by the application. This reflected XSS does not require prior authentication (PR:N) but does require user interaction (UI:R), such as clicking a malicious link. The vulnerability has a CVSS 3.1 base score of 7.1, indicating a high impact with network attack vector (AV:N), low attack complexity (AC:L), and a scope change (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. The impact includes partial confidentiality, integrity, and availability loss (C:L/I:L/A:L). Although no known exploits are currently reported in the wild and no patches have been linked yet, the vulnerability poses a significant risk for phishing, session hijacking, or delivering malware payloads through the affected web application. The lack of proper input validation or output encoding in the User Meta component is the root cause, allowing malicious payloads to be reflected back to users in HTTP responses.

For European organizations using the Khaled User Meta product, this vulnerability could lead to significant security incidents. Reflected XSS can be exploited to steal session cookies, perform unauthorized actions on behalf of users, or redirect users to malicious sites, potentially compromising sensitive personal or corporate data. Given the scope change, attackers might leverage this vulnerability to pivot and affect other parts of the application or network. Organizations in sectors such as finance, healthcare, and government, which handle sensitive user data, are particularly at risk. The exploitation could lead to reputational damage, regulatory fines under GDPR for data breaches, and operational disruptions. Since the vulnerability requires user interaction, targeted phishing campaigns could be used to maximize impact. The absence of known exploits currently provides a window for mitigation, but the high CVSS score indicates that the threat should be treated with urgency.

Organizations should prioritize the following specific actions: 1) Immediately audit and identify all instances of the Khaled User Meta product in their environment, including third-party integrations. 2) Implement strict input validation and output encoding on all user-supplied data within the User Meta component to neutralize malicious scripts. 3) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 4) Educate users and administrators about the risks of clicking untrusted links and recognizing phishing attempts. 5) Monitor web application logs for unusual or suspicious request patterns that may indicate attempted exploitation. 6) Since no official patch is currently available, consider deploying Web Application Firewalls (WAFs) with rules specifically designed to detect and block reflected XSS payloads targeting User Meta. 7) Plan for rapid deployment of vendor patches once released and verify the effectiveness of mitigations through penetration testing and code reviews.
