Executive Summary

The WP Docs plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'wpdocs_options[icon_size]' parameter in all versions up to and including 2.2.9.

This vulnerability exists because the plugin does not properly sanitize input or escape output, allowing authenticated users with subscriber-level access or higher to inject malicious scripts.

These injected scripts execute whenever any user accesses the affected page, potentially compromising user security.

Impact Analysis

This vulnerability can allow attackers with subscriber-level access or above to inject arbitrary web scripts into pages.

When other users visit these pages, the malicious scripts execute in their browsers, which can lead to theft of sensitive information, session hijacking, or other malicious actions.

The CVSS score of 6.4 indicates a medium severity impact, with potential confidentiality and integrity loss but no impact on availability.
