Impact

The ProSolution WP Client WordPress plugin before version 2.0.11 fails to sanitise and escape several parameters before reflecting them into HTML attributes on its public pages. This oversight results in a reflected Cross‑Site Scripting vulnerability that can be triggered against any visitor, including logged‑in administrators, by inserting malicious scripts into the reflected content.

Affected Systems

WordPress sites that have the ProSolution WP Client plugin with a version earlier than 2.0.11. The vulnerability is confined to the plugin; no specific operating system, database, or server details are supplied.

Risk and Exploitability

The CVSS score of 7.1 categorises the flaw as medium‑to‑high severity, while an EPSS score below 1 % indicates a low probability of active exploitation. It is not listed in the CISA KEV catalog. Attackers can exploit the defect by crafting URLs or inputs containing malicious payloads that are reflected into page content, affecting all visitors who load the vulnerable pages.

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the ProSolution WP Client plugin to version 2.0.11 or newer.
  • If an immediate update is not feasible, restrict access to the vulnerable public pages or block the specific parameters through a web application firewall or URL rewrite rules.
  • Ensure that any user‑supplied data that is displayed by the site is properly sanitised or escaped using WordPress functions such as wp_kses or esc_attr to mitigate similar issues in future plugin versions.
