CVE-2025-62095 identifies a Stored Cross-site Scripting (XSS) vulnerability in Neilgee Bootstrap Modals, a component used for modal dialog implementation in web applications. The vulnerability stems from improper neutralization of input during web page generation (CWE-79), allowing malicious scripts to be stored and later executed in the context of users' browsers when they access affected pages. This can lead to unauthorized actions such as session hijacking, credential theft, or manipulation of displayed content. The affected versions include all releases up to 1.3.2, though exact version ranges are unspecified. The CVSS 3.1 base score is 6.5, reflecting network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L) and user interaction (UI:R), with a scope change (S:C) and partial impact on confidentiality, integrity, and availability (C:L/I:L/A:L). No public exploits are known yet, but the vulnerability's presence in a widely used UI component increases potential risk. The issue highlights the importance of proper input validation and output encoding in web components that dynamically generate HTML content. Without remediation, attackers with limited privileges could inject persistent malicious scripts that affect all users accessing the vulnerable modal dialogs.

For European organizations, this vulnerability poses significant risks to web application security, particularly those that integrate Neilgee Bootstrap Modals for user interface dialogs. Successful exploitation can lead to theft of sensitive user data, session tokens, or credentials, enabling further compromise of user accounts and internal systems. It can also facilitate defacement or unauthorized actions within the application, damaging organizational reputation and user trust. The scope change in the vulnerability means that the attack can affect components beyond the immediate vulnerable code, potentially impacting multiple users and systems. Given the widespread use of Bootstrap-based components in European web development, organizations in sectors such as finance, healthcare, e-commerce, and government are especially vulnerable. The lack of known exploits currently provides a window for proactive mitigation, but the medium severity score indicates that exploitation could have tangible adverse effects on confidentiality, integrity, and availability of services.

1. Monitor Neilgee's official channels for patches addressing CVE-2025-62095 and apply updates promptly once released. 2. Implement strict input validation on all data that can be rendered within Bootstrap Modals, ensuring that potentially malicious scripts or HTML are sanitized or rejected. 3. Employ robust output encoding techniques when generating dynamic content to prevent script injection. 4. Deploy Content Security Policy (CSP) headers to restrict execution of unauthorized scripts and reduce impact of XSS attacks. 5. Conduct comprehensive code reviews focusing on areas where user input is incorporated into modal dialogs. 6. Use security testing tools such as automated scanners and manual penetration testing to detect stored XSS vulnerabilities in web applications. 7. Educate developers on secure coding practices related to DOM manipulation and input handling in UI components. 8. Consider implementing web application firewalls (WAFs) with rules designed to detect and block XSS payloads targeting modal dialogs. 9. Limit privileges of users and services interacting with vulnerable components to reduce potential attack surface. 10. Maintain regular backups and incident response plans to quickly recover from any successful exploitation.
