The WP Team – WordPress Team Member Plugin for WordPress versions up to 1.1.4 contains a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the htteamember shortcode. Authenticated attackers with contributor or higher privileges can inject arbitrary JavaScript code via insufficiently sanitized user input, which is then stored and executed in the context of users viewing the affected pages. This vulnerability allows for potential compromise of user sessions or other client-side impacts. The CVSS 3.1 base score is 6.4 (medium), reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial confidentiality and integrity impact without availability impact. No patch or remediation details are currently provided by the vendor.

An attacker with contributor-level or higher access can inject malicious scripts that execute in the browsers of users who view the compromised pages. This can lead to partial confidentiality and integrity impacts, such as session hijacking or unauthorized actions performed on behalf of users. There is no indication of availability impact. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the WP Team – WordPress Team Member Plugin if feasible. Monitor official vendor channels for updates or patches addressing this vulnerability.
