What the vulnerability does
The Menu Card plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `category` parameter in all versions up to, and including, 0.8.0 due to insufficient input sanitization and output escaping. 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
Menu Card versions 0.8.0 and earlier contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning injected code can affect other users and site functionality. An attacker with low-level account access can craft malicious input that executes in other users' browsers when they view affected content.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors and site operations; user accounts and data may be compromised.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
