WordPress Google XML News Sitemap Plugin Cross-Site Request Forgery Vulnerability Allowing Stored Cross-Site Scripting

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the WordPress Google XML News Sitemap plugin, specifically in versions through 0.02. This vulnerability allows for Stored Cross-Site Scripting (XSS) attacks. The issue arises from the plugin's failure to properly validate requests, enabling attackers to trick users with higher privileges into performing actions that could inject malicious scripts, which are then stored and executed later.

Impact

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

Remediation

Users are advised to remove and replace this plugin, as it is likely abandoned and will not receive further updates or fixes.
