WordPress Simple Add Pages or Posts Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Simple Add Pages or Posts plugin for WordPress, affecting all versions prior to and including 2.0.0. The vulnerability arises from inadequate input sanitization and output escaping, allowing authenticated attackers with administrator-level access to inject arbitrary web scripts into pages. These scripts would execute when a user accesses the compromised page. This issue is present in multi-site installations and those 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.
