FastBots WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the FastBots plugin for WordPress, affecting all versions through 1.0.12. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level permissions to inject arbitrary scripts. These scripts are executed when users access the compromised pages. This vulnerability is present in multi-site installations where the unfiltered_html capability 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 affected page.
