CVE-2025-48110 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the mibuthu Link View product up to version 0.8.0. Stored XSS occurs when malicious input is improperly neutralized during web page generation and is persistently stored on the server, later served to users without adequate sanitization or encoding. This vulnerability allows an attacker with low privileges (PR:L) to inject malicious scripts that execute in the context of other users' browsers when they view the affected content. The CVSS 3.1 base score of 6.5 reflects a medium severity, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact affects confidentiality, integrity, and availability at a low level, as the attacker can execute scripts that may steal session tokens, manipulate displayed data, or perform actions on behalf of the user. No known exploits are currently reported in the wild, and no patches are listed yet. The vulnerability was reserved in May 2025 and published in August 2025, indicating recent discovery. The lack of patch links suggests that organizations using mibuthu Link View should be vigilant and prepare to apply fixes once available. Stored XSS vulnerabilities are dangerous because they can affect multiple users and persist until remediated, potentially leading to account compromise, data theft, or further exploitation within the affected environment.

For European organizations using mibuthu Link View, this vulnerability poses a risk of session hijacking, unauthorized actions, and data leakage through malicious script execution in users' browsers. Given the medium severity, the impact could disrupt business operations, damage user trust, and lead to compliance issues under regulations such as GDPR if personal data is compromised. The requirement for low privileges and user interaction means that internal users or authenticated clients could be targeted to escalate attacks. Organizations in sectors with high web application usage, such as finance, healthcare, and public services, may face increased risk due to the potential for sensitive data exposure and reputational damage. The scope change indicates that the vulnerability could affect other components or data beyond the initial application, increasing the potential attack surface. Although no exploits are known in the wild, the presence of this vulnerability should prompt proactive risk assessments and mitigation to prevent exploitation, especially in environments with multiple users accessing the Link View interface.

1. Implement strict input validation and output encoding on all user-supplied data within mibuthu Link View, focusing on HTML, JavaScript, and URL contexts to prevent script injection. 2. Apply Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 3. Monitor user activity and logs for unusual behavior indicative of XSS exploitation attempts, such as unexpected script execution or anomalous requests. 4. Restrict privileges to the minimum necessary for users interacting with Link View to reduce the attack surface. 5. Educate users about the risks of clicking on suspicious links or interacting with untrusted content within the application. 6. Stay updated with mibuthu vendor communications for patches or updates addressing this vulnerability and apply them promptly once available. 7. Consider deploying web application firewalls (WAF) with rules tuned to detect and block XSS payloads targeting Link View. 8. Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including XSS, to identify and remediate issues proactively.
