CVE-2025-68890 is a DOM-based Cross-site Scripting (XSS) vulnerability identified in the hands01 e-shops e-shops-cart2 product, affecting versions up to and including 1.0.4. The vulnerability stems from improper neutralization of user-supplied input during web page generation, specifically in the client-side DOM context. Unlike traditional reflected or stored XSS, DOM-based XSS occurs entirely on the client side, where malicious scripts are injected and executed by manipulating the Document Object Model. This flaw allows attackers to craft malicious URLs or inputs that, when processed by the vulnerable e-shops-cart2 interface, execute arbitrary JavaScript in the victim's browser. Potential consequences include session hijacking, credential theft, unauthorized transactions, or redirection to malicious sites. The vulnerability does not require authentication, increasing its risk profile. No CVSS score is assigned yet, and no known exploits have been reported in the wild. The vulnerability was reserved in late December 2025 and published in early January 2026, indicating recent discovery and disclosure. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for immediate attention from affected users.

For European organizations using the hands01 e-shops platform, this DOM-based XSS vulnerability poses significant risks. Exploitation can compromise the confidentiality of customer data, including personal and payment information, by enabling attackers to steal session cookies or credentials. Integrity may be affected as attackers could manipulate transactions or display fraudulent content to users. Availability impact is generally limited for XSS but could extend to denial-of-service if exploited in combination with other vulnerabilities. The reputational damage from a successful attack could lead to loss of customer trust and potential regulatory fines under GDPR for failure to protect user data. E-commerce businesses relying on this platform may face financial losses and increased scrutiny. The absence of known exploits provides a window for proactive mitigation, but the vulnerability's client-side nature makes detection and prevention challenging without proper controls.

Organizations should immediately audit their use of the hands01 e-shops e-shops-cart2 component and restrict exposure where possible. Implement strict input validation and output encoding on all user-controllable inputs, especially those reflected in the DOM. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Monitor web application logs and user reports for suspicious activity indicative of XSS exploitation attempts. Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. In the interim, consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block DOM-based XSS payloads. Educate developers on secure coding practices to prevent similar client-side injection flaws. Regularly review and update security policies to include client-side security assessments.
