CVE-2025-68457 is a cross-site scripting vulnerability identified in Orejime, a consent management tool developed by boscop-fr that emphasizes accessibility. The vulnerability arises from improper neutralization of input during web page generation (CWE-79). Specifically, in Orejime versions before 2.3.2, HTML elements managed by Orejime could be manipulated if an attacker managed to inject malicious HTML containing data attributes with embedded 'javascript:' URIs. When a user consents to the related purpose, Orejime converts these data attributes (e.g., 'data-href') into standard attributes (e.g., 'href'), causing the embedded JavaScript to execute in the user's browser context. This execution can lead to theft of session tokens, unauthorized actions, or other malicious behaviors typical of XSS attacks. However, the exploitability is limited because Orejime elements are generally hardcoded, making HTML injection a prerequisite for exploitation. The vulnerability has been addressed in Orejime version 2.3.2 by preventing such attribute conversion or sanitizing inputs. The CVSS 4.0 score of 0.6 reflects a low severity due to the need for user interaction, lack of authentication requirement, and limited scope of affected systems. No active exploits have been reported. Mitigation outside of updating Orejime includes sanitizing any user-controllable attributes that could be converted into executable attributes to prevent script execution.

For European organizations, the impact of this vulnerability is generally low but context-dependent. If an organization uses Orejime versions prior to 2.3.2 in web applications that allow user-supplied content or insufficiently sanitized inputs, attackers could exploit this XSS vulnerability to execute malicious scripts in users' browsers. This could lead to session hijacking, unauthorized actions, or phishing attacks targeting users of the affected web applications. However, since Orejime elements are typically hardcoded and the vulnerability requires HTML injection, the attack surface is limited. Organizations with high compliance requirements for user privacy and consent management, such as those in the EU under GDPR, may face reputational damage or regulatory scrutiny if such vulnerabilities are exploited. The low CVSS score indicates limited direct impact on system confidentiality, integrity, or availability, but the risk to user data and trust remains. The absence of known exploits reduces immediate risk but does not eliminate the need for remediation.

1. Upgrade Orejime to version 2.3.2 or later immediately to apply the official patch that addresses this vulnerability. 2. Implement strict input validation and sanitization on all user-supplied content, especially any HTML or attributes that could be converted into executable code. Use well-established libraries or frameworks for sanitization that specifically neutralize 'javascript:' URIs and other executable content. 3. Employ Content Security Policy (CSP) headers to restrict the execution of inline scripts and limit the sources of executable code in the browser context. 4. Conduct regular security code reviews and penetration testing focused on client-side injection vectors in web applications using Orejime. 5. Educate developers and administrators about the risks of improper attribute handling and the importance of sanitizing dynamic content. 6. Monitor web application logs and user reports for signs of suspicious activity or attempted XSS exploitation. 7. If upgrading Orejime is not immediately possible, apply temporary server-side sanitization filters to remove or neutralize potentially dangerous attributes before rendering pages.
