The Employee Directory – Staff Listing & Team Directory WordPress plugin suffers from a stored cross-site scripting vulnerability (CWE-79) in its 'emd_mb_meta' shortcode. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript code due to improper input sanitization and output escaping of user-supplied attributes. This malicious code executes in the context of any user who accesses the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability is present in all versions up to 4.5.0. No patch or official remediation information is currently available.

Successful exploitation allows an authenticated user with contributor-level access or higher to inject persistent malicious scripts into pages rendered by the plugin. These scripts execute in the browsers of users who visit the infected pages, potentially compromising user sessions and data confidentiality. The vulnerability does not impact availability. The CVSS score of 6.4 reflects a medium impact on confidentiality and integrity with no impact on availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin if possible.
