The Employee Directory – Staff & Team Directory plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) via the 'noaccess_msg' parameter. This flaw allows authenticated users with Contributor or higher privileges to inject arbitrary JavaScript code into pages, which executes in the context of other users viewing those pages. The vulnerability affects all versions up to 4.5.1 due to improper input neutralization during web page generation. The CVSS 3.1 score is 6.4, reflecting a medium impact with network attack vector, low attack complexity, and no user interaction required. The vulnerability impacts confidentiality and integrity but not availability. No patch or official fix information is provided in the data.

Successful exploitation allows an authenticated user with Contributor-level access or above to inject persistent malicious scripts into the plugin's pages. These scripts execute in the browsers of users who view the injected content, potentially leading to unauthorized actions or data disclosure within the context of the affected site. The impact is limited to confidentiality and integrity, with no direct availability impact. There are no known exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the Employee Directory plugin if possible. Monitor vendor channels for updates and apply patches promptly once released.
