CVE-2025-47668 is a medium-severity vulnerability classified as CWE-79, which corresponds to Cross-site Scripting (XSS) due to improper neutralization of input during web page generation in the CookieCode product by cookiecode. Specifically, this vulnerability allows for Stored XSS attacks, meaning that malicious scripts injected by an attacker can be permanently stored on the target server and executed in the browsers of users who access the affected pages. The vulnerability affects versions of CookieCode up to and including 2.4.4, although the exact range is not fully specified (noted as 'n/a' through 2.4.4). The CVSS 3.1 base score is 5.9, indicating a medium level of severity. The vector string (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be performed remotely over the network with low attack complexity but requires high privileges and user interaction. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component. The impact on confidentiality, integrity, and availability is low to moderate. Stored XSS vulnerabilities can lead to session hijacking, defacement, or redirection to malicious sites, potentially compromising user data and trust. However, the requirement for high privileges and user interaction reduces the ease of exploitation. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on May 7, 2025, and is enriched by CISA, indicating recognition by US cybersecurity authorities. CookieCode is a web application or framework component used for cookie management, likely integrated into websites to handle cookie consent or related functionality.

For European organizations, the impact of this vulnerability depends on their use of CookieCode in their web infrastructure. Organizations that deploy CookieCode for cookie management or related web services could be exposed to stored XSS attacks, which can compromise user sessions, steal sensitive information, or manipulate website content. This can lead to reputational damage, loss of user trust, and potential regulatory penalties under GDPR if personal data is compromised. The requirement for high privileges to exploit the vulnerability suggests that attackers may need to have some level of access to the system or authenticated user accounts, which somewhat limits the risk from external attackers but raises concerns about insider threats or compromised accounts. The need for user interaction means phishing or social engineering could be used to trigger the exploit. Given the widespread enforcement of data protection laws and the importance of web security in Europe, even medium-severity vulnerabilities like this can have significant operational and compliance consequences.

1. Immediate review and audit of all web applications using CookieCode to identify affected versions. 2. Apply any available patches or updates from the vendor as soon as they are released; if no official patch exists, consider temporary mitigations such as disabling vulnerable features or modules. 3. Implement strict input validation and output encoding on all user-supplied data, especially data that is stored and later rendered in web pages, to prevent injection of malicious scripts. 4. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 5. Enforce the principle of least privilege to limit user and process permissions, reducing the risk posed by high-privilege accounts. 6. Conduct user awareness training to reduce the risk of social engineering attacks that could trigger the stored XSS. 7. Monitor web application logs and user activity for suspicious behavior indicative of exploitation attempts. 8. Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS payloads as an additional layer of defense.
