CVE-2025-10701 identifies a stored Cross-Site Scripting (XSS) vulnerability in the Time Clock – A WordPress Employee & Volunteer Time Clock Plugin, versions up to and including 1.3.1. The vulnerability arises from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'data' parameter supplied by authenticated users. This flaw allows attackers with Time Clock user credentials to inject arbitrary JavaScript code that is stored persistently and executed in the context of other users viewing the affected pages. The attack vector requires authentication but no user interaction beyond accessing the compromised page. The vulnerability impacts confidentiality and integrity by enabling session hijacking, credential theft, or unauthorized actions performed on behalf of legitimate users. The CVSS 3.1 score of 6.4 reflects a medium severity, with network attack vector, low attack complexity, and privileges required. No patches or known exploits are currently available, but the vulnerability is publicly disclosed. The plugin is commonly used in WordPress environments for employee and volunteer time tracking, making it a target for attackers aiming to leverage trusted internal systems for lateral movement or data exfiltration.

For European organizations, this vulnerability poses a risk primarily to those using the affected Time Clock plugin on WordPress sites for workforce management. Exploitation could lead to unauthorized script execution, enabling attackers to hijack user sessions, steal sensitive employee or volunteer data, or perform unauthorized actions within the plugin or broader WordPress environment. This can result in data breaches, loss of integrity of time tracking records, and potential compliance violations under GDPR due to unauthorized access to personal data. The medium severity indicates a moderate risk, but the requirement for authenticated access limits exposure to internal or trusted users, such as employees or volunteers with Time Clock credentials. However, insider threats or compromised credentials could be leveraged to exploit this vulnerability. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure. Organizations relying on this plugin should consider the potential impact on operational continuity and data confidentiality.

1. Monitor the plugin vendor’s announcements closely and apply official patches immediately once available. 2. Until a patch is released, restrict access to the Time Clock plugin to only trusted users and minimize the number of users with Time Clock credentials. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting the 'data' parameter. 4. Conduct manual code review or use security plugins to enforce strict input validation and output encoding on the 'data' parameter to neutralize malicious scripts. 5. Educate users with Time Clock access about phishing and credential security to reduce the risk of compromised accounts. 6. Regularly audit WordPress user roles and permissions to ensure least privilege principles are enforced. 7. Consider isolating the WordPress environment or using containerization to limit the impact of any successful exploitation. 8. Enable logging and monitoring to detect anomalous activities related to the plugin usage.
