CVE-2025-64362 identifies a DOM-based Cross-site Scripting (XSS) vulnerability in the SeventhQueen K Elements product, affecting all versions prior to 5.5.0. This vulnerability stems from improper neutralization of input during web page generation, where user-controllable data is incorporated into the DOM without adequate sanitization or encoding. As a result, attackers can craft malicious payloads that execute arbitrary JavaScript in the context of the victim's browser when they interact with the affected web pages. The vulnerability is exploitable remotely over the network (AV:N), with low attack complexity (AC:L), but requires privileges (PR:L) and 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 to a limited extent (C:L/I:L/A:L). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the potential for session hijacking, credential theft, or manipulation of web content. SeventhQueen K Elements is a web content generation tool used in various enterprise environments, and the vulnerability could be leveraged to target users of affected web applications. The lack of available patches at the time of publication necessitates immediate attention to mitigation strategies. The CVSS v3.1 base score of 6.5 categorizes this as a medium severity issue, reflecting the balance between ease of exploitation and the requirement for privileges and user action.

For European organizations, this vulnerability presents a moderate risk primarily to web applications built using SeventhQueen K Elements prior to version 5.5.0. Successful exploitation could lead to unauthorized disclosure of sensitive information, such as session tokens or personal data, through script injection. Integrity of web content can be compromised, potentially misleading users or facilitating further attacks like phishing or malware distribution. Availability impacts, while limited, could arise from script-based disruptions or denial-of-service conditions triggered by malicious payloads. Sectors such as finance, healthcare, and government, which often rely on web-based portals and sensitive data handling, are particularly vulnerable. The requirement for privileges and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments with multiple user roles and frequent external interactions. Additionally, the cross-site scripting nature of the vulnerability could be exploited to bypass same-origin policies, increasing the potential for lateral movement within affected networks. The absence of known exploits in the wild provides a window for proactive defense, but also underscores the importance of swift remediation to prevent future attacks.

1. Monitor SeventhQueen communications and apply official patches for K Elements 5.5.0 or later immediately upon release. 2. Until patches are available, implement strict input validation and output encoding on all user-controllable data incorporated into web pages, focusing on DOM contexts. 3. Deploy Content Security Policies (CSP) to restrict execution of unauthorized scripts and reduce the impact of potential XSS payloads. 4. Conduct thorough code reviews and security testing of web applications using K Elements to identify and remediate unsafe DOM manipulations. 5. Educate users about the risks of interacting with untrusted links or content that could trigger XSS attacks, especially in privileged roles. 6. Utilize web application firewalls (WAFs) with rules targeting DOM-based XSS patterns to provide an additional layer of defense. 7. Limit privileges of users and services interacting with K Elements to the minimum necessary to reduce the attack surface. 8. Monitor logs and network traffic for unusual activities indicative of exploitation attempts, such as anomalous script execution or unexpected requests.
