What the vulnerability does
The WP to LinkedIn Auto Publish plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via PostMessage in all versions up to, and including, 1.9.8 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms

An attacker can inject malicious scripts that execute in the browsers of site administrators and other users. The vulnerability requires user interaction—typically clicking a malicious link or visiting a compromised page. Successful exploitation can lead to account compromise or unauthorized actions on the site.
What an attacker can do
Inject malicious scripts that run in users' browsers when they view affected pages or content.
Potential impact on your site
