Publication date: 2026-08-12

Last updated on: 2026-08-26

Assigner: WPScan

Description

The ProSolution WP Client WordPress plugin before 2.0.9 does not validate a user-supplied URL, and does not check the capability or nonce of the requester, before performing a server-side HTTP request with it, allowing any authenticated user, such as a subscriber, to make the site issue arbitrary requests to internal hosts and services, including requests with an attacker-chosen method, headers and body.

Attack-Flow Graph

Executive Summary

This is a Server-Side Request Forgery (SSRF) vulnerability in the ProSolution WP Client WordPress plugin before version 2.0.9. It allows any authenticated user, including subscribers, to send arbitrary HTTP requests to internal hosts and services by exploiting the unvalidated proSol_url_validate parameter. The plugin fails to check user capabilities or request nonces before making server-side HTTP requests.

Detection Guidance

Check the installed version of the ProSolution WP Client plugin. If it is below 2.0.9, the vulnerability is likely present. Use commands like 'wp plugin list' in WordPress CLI or inspect the plugin files for version details.

Impact Analysis

An attacker could exploit this to access internal services, exfiltrate data, or perform unauthorized actions on behalf of the server. Since any authenticated user can trigger requests, it increases the risk of internal network probing or data leakage.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating confidentiality requirements in GDPR and HIPAA. It may result in non-compliance due to potential breaches of protected data.

Mitigation Strategies

Update the ProSolution WP Client plugin to version 2.0.9 or later immediately. Remove or disable the plugin if an update is not available. Restrict user roles to prevent unauthorized access.
