The Employee Spotlight – Team Member Showcase & Meet the Team plugin for WordPress, developed by emarket-design, suffers from a missing authorization vulnerability identified as CVE-2025-13403 (CWE-862). The vulnerability exists in the employee_spotlight_check_optin() function, which handles the enabling or disabling of tracking settings within the plugin. Due to the lack of proper authorization checks, any authenticated user with at least Subscriber-level privileges can modify these tracking settings. This flaw affects all plugin versions up to and including 5.1.3. The vulnerability is remotely exploitable over the network without requiring user interaction or elevated privileges beyond Subscriber access. The CVSS v3.1 base score is 5.3, reflecting a medium severity primarily due to the integrity impact on tracking configurations, with no direct confidentiality or availability consequences. No patches or known exploits have been reported at the time of publication. The vulnerability could be leveraged to alter tracking behavior, potentially undermining privacy controls or data collection accuracy within affected WordPress sites.

The primary impact of this vulnerability is the unauthorized modification of tracking settings within the affected WordPress plugin. While it does not directly expose sensitive data or disrupt service availability, altering tracking configurations can have significant implications for organizations relying on accurate analytics or compliance with privacy regulations such as GDPR or CCPA. Attackers with Subscriber-level access could disable tracking to evade monitoring or enable tracking to collect unauthorized data, potentially leading to privacy violations or inaccurate user behavior insights. This could undermine trust in the website’s data integrity and complicate incident response or auditing efforts. Organizations with multiple users having Subscriber or higher roles are at increased risk, as any compromised or malicious low-privilege user could exploit this vulnerability.

To mitigate this vulnerability, organizations should first update the Employee Spotlight plugin to a version that includes proper authorization checks once available from the vendor. Until a patch is released, administrators should restrict Subscriber-level access and review user roles to minimize the number of users with permissions that could exploit this flaw. Implementing a Web Application Firewall (WAF) with custom rules to detect and block unauthorized requests targeting the employee_spotlight_check_optin() function may reduce risk. Monitoring plugin configuration changes and enabling audit logging for user actions can help detect exploitation attempts. Additionally, organizations should review and enforce strict access control policies for WordPress user roles and consider disabling or replacing the plugin if it is not essential. Regular security assessments and plugin inventory reviews will help identify and remediate similar risks proactively.
