Smart Docs WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Smart Docs plugin for WordPress, affecting all versions through 1.1.1. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level permissions to inject arbitrary scripts into pages. These scripts execute when users access the affected pages. This vulnerability is present in multi-site installations where unfiltered_html has been disabled.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
