What the vulnerability does
The Wp chart generator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpchart shortcode in all versions up to, and including, 1.0.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
WP Chart Generator versions 1.0.4 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability affects the site's scope, meaning injected code can impact other users and site functionality. An attacker with low-level access can craft malicious input that executes in other users' browsers when they view affected pages.
What an attacker can do
Inject JavaScript that runs in other users' browsers and affects site functionality.
Potential impact on your site
Authenticated users can inject malicious scripts affecting other visitors and site operations.
Conditions required to exploit
Attacker must have a low-privilege user account (e.g., subscriber or contributor role).
