The ProSolution WP Client WordPress plugin before 2.0.11 does not sanitise and escape several parameters before reflecting them into HTML attributes on its public pages, leading to reflected Cross-Site Scripting that can be triggered against any visitor, including a logged-in administrator.
AI Analysis
Technical Summary
The ProSolution WP Client WordPress plugin before version 2.0.11 contains a reflected XSS vulnerability due to improper sanitization and escaping of multiple parameters that are reflected into HTML attributes on public-facing pages. This vulnerability can be triggered against any visitor, including administrators, potentially allowing script execution in their browsers.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary JavaScript in the context of the affected site for any visitor, including logged-in administrators. This may lead to session hijacking, defacement, or other malicious actions performed with the privileges of the victim user.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability affects versions prior to 2.0.11, upgrading to version 2.0.11 or later is recommended once official confirmation is available. Until then, avoid exposing the vulnerable parameters or restrict access to trusted users if possible.
