CVE-2025-13584 is a cross-site scripting (XSS) vulnerability identified in the Eigenfocus software product, affecting all versions up to and including 1.4.0. The flaw exists in the Description Handler component, where the parameters entry.description and time_entry.description are not properly sanitized, allowing an attacker to inject malicious JavaScript code. This vulnerability can be exploited remotely without requiring authentication, although user interaction is necessary to trigger the malicious script, such as by viewing a crafted description field. The vulnerability does not compromise confidentiality or availability directly but can lead to session hijacking, credential theft, or execution of arbitrary scripts in the context of the victim’s browser, potentially facilitating phishing or further attacks. The vulnerability was publicly disclosed on November 24, 2025, with exploit code available, increasing the risk of exploitation. The vendor has addressed the issue in Eigenfocus version 1.4.1, with a patch identified by commit 7dec94c9d1f3e513e0ee38ba68caaba628e08582. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, but user interaction is needed, with limited impact on integrity and no impact on confidentiality or availability. No known exploits in the wild have been reported yet, but the public disclosure necessitates prompt remediation.

For European organizations, the primary impact of CVE-2025-13584 lies in the potential for attackers to execute malicious scripts within the context of users’ browsers when interacting with vulnerable Eigenfocus instances. This can lead to session hijacking, unauthorized actions on behalf of users, theft of sensitive information such as authentication tokens, or delivery of phishing payloads. Organizations relying on Eigenfocus for project management or time tracking may face risks to user accounts and data integrity. While the vulnerability does not directly affect system availability or confidentiality at a broad level, the indirect consequences of successful XSS attacks can be significant, including reputational damage and compliance violations under GDPR if personal data is compromised. The remote exploitability and public availability of exploit code increase the urgency for European entities to patch promptly. Additionally, sectors with high reliance on Eigenfocus, such as IT services, consulting firms, and public sector organizations, may be targeted to gain footholds for further attacks.

1. Immediate upgrade of Eigenfocus installations to version 1.4.1 or later, which contains the official patch for CVE-2025-13584. 2. Implement strict input validation and output encoding on all user-supplied data fields, especially those related to descriptions or text entries, to prevent injection of malicious scripts. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing Eigenfocus. 4. Conduct security awareness training for users to recognize and avoid interacting with suspicious or unexpected content within the application. 5. Monitor web application logs for unusual input patterns or repeated attempts to inject scripts in the vulnerable parameters. 6. Use web application firewalls (WAFs) with updated rules to detect and block XSS attack payloads targeting Eigenfocus. 7. Regularly review and audit third-party components and dependencies for security updates to reduce exposure to similar vulnerabilities.
