CVE-2025-68538 is a DOM-based Cross-site Scripting (XSS) vulnerability identified in ThemeGoods Craft, a content management system widely used for building websites. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious actors to inject and execute arbitrary JavaScript code within the context of the victim’s browser session. This type of XSS is client-side and occurs when the web application’s client-side scripts process untrusted data without proper sanitization or encoding. Affected versions include all Craft versions up to and including 2.3.6. The vulnerability has a CVSS v3.1 base score of 7.1, reflecting high severity due to its network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact affects confidentiality, integrity, and availability, as attackers can steal session tokens, manipulate page content, or perform actions on behalf of users. No patches or exploit code are currently publicly available, but the vulnerability is published and should be treated as a significant risk. The vulnerability is particularly relevant for websites that rely on Craft for dynamic content generation and user interaction, such as e-commerce, media, and corporate sites.

For European organizations, this vulnerability poses a substantial risk to web applications built on ThemeGoods Craft, especially those handling sensitive user data or financial transactions. Successful exploitation can lead to session hijacking, credential theft, unauthorized actions, and defacement, undermining user trust and potentially causing regulatory compliance issues under GDPR due to data breaches. The availability of the affected product in European markets, combined with the widespread use of CMS platforms in sectors like retail, media, and government, increases the potential attack surface. The requirement for user interaction means phishing or social engineering campaigns could be used to trigger the exploit. The vulnerability’s ability to affect confidentiality, integrity, and availability simultaneously elevates its threat level. Organizations may face reputational damage, financial losses, and legal consequences if exploited. Given the lack of known exploits, proactive mitigation is critical to prevent future attacks.

European organizations should immediately assess their use of ThemeGoods Craft and identify any instances running versions up to 2.3.6. Although no official patches are currently linked, organizations should monitor vendor announcements for updates and apply them promptly once available. In the interim, implement strict input validation and output encoding on all user-supplied data, especially data rendered in the DOM. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS payloads. Conduct security awareness training to educate users about the risks of clicking untrusted links or interacting with suspicious content. Employ web application firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting Craft CMS. Regularly audit and test web applications for XSS vulnerabilities using automated scanners and manual penetration testing. Finally, implement robust logging and monitoring to detect anomalous activities that may indicate exploitation attempts.
