WordPress Spoiler Block Plugin Cross-Site Request Forgery Vulnerability Allowing Stored Cross-Site Scripting

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the WordPress Spoiler Block plugin, specifically in versions through 1.7. This vulnerability allows for Stored Cross-Site Scripting (XSS) attacks. The issue arises because the plugin does not properly validate requests, enabling attackers to trick users with higher privileges into performing actions that could inject malicious scripts into the site.

Impact

Exploitation of this vulnerability could lead to Stored Cross-Site Scripting, where injected scripts are executed in the context of the user.
