CVE-2025-8092 is a Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the Drupal COOKiES Consent Management module versions prior to 1.2.16. This vulnerability arises due to improper neutralization of input during web page generation, allowing malicious actors to inject and execute arbitrary scripts in the context of a victim's browser session. Specifically, the flaw exists in how user-supplied input is handled and rendered by the COOKiES Consent Management module, which is responsible for managing cookie consent banners and related user interactions on Drupal-based websites. Exploiting this vulnerability could enable attackers to perform actions such as session hijacking, defacement, phishing, or redirecting users to malicious sites. Although no known exploits are currently reported in the wild, the nature of XSS vulnerabilities makes them attractive targets for attackers, especially on high-traffic websites. The vulnerability affects all versions from 0.0.0 up to but not including 1.2.16, indicating that a patch or update addressing this issue has been released but not yet linked in the provided data. The absence of a CVSS score requires an independent severity assessment based on the potential impact and exploitability factors.

For European organizations, this vulnerability poses significant risks, particularly for entities relying on Drupal-based websites that utilize the COOKiES Consent Management module to comply with stringent EU cookie and privacy regulations such as the GDPR. Successful exploitation could lead to unauthorized access to user sessions, leakage of sensitive personal data, and erosion of user trust. This is especially critical for sectors like finance, healthcare, e-commerce, and government services where personal data protection is paramount. Additionally, compromised websites could be used as vectors for broader phishing campaigns or malware distribution, amplifying the threat landscape. The reputational damage and potential regulatory penalties resulting from data breaches or non-compliance with privacy laws could be substantial. Given the widespread use of Drupal in Europe and the mandatory nature of cookie consent mechanisms, the impact could be broad and severe if left unmitigated.

European organizations should immediately verify the version of the COOKiES Consent Management module in use and upgrade to version 1.2.16 or later where the vulnerability is addressed. In the absence of an official patch, organizations should implement strict input validation and output encoding on all user-supplied data rendered by the module to neutralize potentially malicious scripts. Employing Content Security Policy (CSP) headers can further mitigate the risk by restricting the execution of unauthorized scripts. Regular security audits and penetration testing focused on XSS vulnerabilities should be conducted, especially on modules handling user input. Additionally, monitoring web traffic for unusual activity and educating web administrators about secure coding practices will help reduce the attack surface. Organizations should also ensure that their incident response plans include procedures for handling XSS exploitation scenarios to minimize damage.
