CVE-2025-49310 is a stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the M A Vinoth Kumar Frontend Dashboard product up to version 2.2.8. The vulnerability arises due to improper neutralization of input during web page generation, allowing malicious scripts to be injected and stored within the application. When other users access the affected pages, these scripts execute in their browsers, potentially leading to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. The CVSS 3.1 base score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), user interaction (UI:R), scope changed (S:C), and low impact on confidentiality, integrity, and availability (C:L/I:L/A:L). This means an attacker with some level of authenticated access can exploit this vulnerability remotely, but user interaction is necessary for the attack to succeed, and the impact affects resources beyond the vulnerable component. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability is significant because stored XSS can be leveraged for persistent attacks against users of the dashboard, especially in environments where sensitive data or administrative functions are accessible through the frontend interface.

For European organizations using the M A Vinoth Kumar Frontend Dashboard, this vulnerability poses a risk of persistent client-side code injection, which can lead to unauthorized access to user sessions, theft of sensitive information, and potential manipulation of dashboard data or functions. Given that the vulnerability requires some level of authenticated access and user interaction, insider threats or compromised user accounts could be leveraged to exploit this flaw. The scope change in the CVSS vector indicates that the impact extends beyond the vulnerable component, potentially affecting other parts of the system or network. In sectors such as finance, healthcare, or critical infrastructure within Europe, where dashboards often provide operational control or sensitive data visualization, exploitation could disrupt business processes or lead to data breaches. The medium severity rating suggests a moderate but non-negligible risk, especially if exploited in targeted attacks. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, emphasizing the need for proactive mitigation.

European organizations should implement the following specific mitigation measures: 1) Apply input validation and output encoding rigorously on all user-supplied data within the Frontend Dashboard to prevent script injection. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3) Enforce the principle of least privilege for user accounts to limit the potential for authenticated attackers to inject malicious content. 4) Monitor and audit user inputs and dashboard content for suspicious or anomalous entries that could indicate attempted exploitation. 5) Implement multi-factor authentication (MFA) to reduce the risk of compromised credentials being used to exploit this vulnerability. 6) Stay alert for official patches or updates from the vendor and apply them promptly once available. 7) Educate users about the risks of interacting with untrusted content and encourage cautious behavior when clicking links or interacting with dashboard elements. 8) Consider deploying web application firewalls (WAFs) with rules tuned to detect and block XSS payloads targeting the Frontend Dashboard.
